Johns Pass Bridge transition from the 1971 to 2008 spans

 

Introduction

Created by a hurricane way back in 1848, Johns Pass was named after John LeVeque who visited the area to hide some treasures he had amassed earlier.  When John LeVeque tried to retrieve his treasure the hurricane of 1848 came through and created the passage between Boca Ciega Bay and the Gulf of Mexico where it is believed the treasure was buried.

The original Johns Pass Bridge was constructed probably in the late 1920's or early 1930's and was a low-level two-lane drawbridge carrying Gulf Blvd. (FL 699) between Treasure Island and Madeira Beach and served its purpose for many years.  However, growth in the immediate Johns Pass area and the strong currents within Johns Pass forced the Florida DOT to consider a new twin span Johns Pass Bridge built on a different alignment to avoid the many shops sprouting up on Gulf Blvd. in the immediate vicinity of Johns Pass.

A new twin-span drawbridge was constructed and opened in 1971, with the original span to the east demolished shortly thereafter.  Even though the pier bents were designed squarely with the current, the Johns Pass Bridge began seeing scouring problems as back as 1981.  Additional piers were installed underneath the existing pier bents so that the piers would not sink.

Unlike most other drawbridges in Pinellas County where openings are restricted to a time schedule, the Johns Pass Bridge opens on demand and for a very good reason:  The swift current prevalent in Johns Pass.  The frequent yet justified bridge openings have had motorists waiting lengthy periods to get across.  One business just immediately south of Johns Pass advertised drinks for 50 cents if the bridge was up.

Work began in 2006 on replacing the current Johns Pass Bridge with a twin span of new drawbridges.  As of December 2007 work is progressing on the southbound bridge and when the southbound bridge is done, the northbound bridge will be reconstructed on the same alignment.  However, the center drawbridge section will be elevated a little higher so that less openings can take place.

My idea for replacing the Johns Pass Bridge

As of December 2007 work is progressing on replacing the twin drawbridges of the Johns Pass Bridge with new drawbridges which will be higher and on the same alignment.  However, I have two ideas which I believe would have been better than replacing an existing drawbridge with a new drawbridge with a higher vertical clearance, given the heavy traffic frequenting the bridge especially during the tourist season.

1.  High level fixed bridge:  This would have proven ideal not only for vehicular and pedestrian traffic but for boating traffic as well.  Traffic would not be inconvenienced by the constant bridge openings and boaters would not have to be waiting in the swift current of Johns Pass.  However, a high level fixed bridge at Johns Pass would bring strong opposition to the immediate community in that a fixed level bridge would obstruct pristine views of the Gulf of Mexico and its beaches.

2.  Tunnel:  Ft. Lauderdale has the only vehicular tunnel in the State of Florida, and it's under the New River which carries US 1 south of downtown Ft. Lauderdale.  I believe the tunnel replaced a drawbridge which had been in operation for many years and motorists were becoming annoyed of the inconveniences when the bridge is opened.  Why couldn't a tunnel be an option for Johns Pass?

A tunnel would preserve the pristine beach views enjoyed by the immediate Johns Pass community as well as have the Johns Pass Village and Boardwalk blend in with the character of the area.  However, a tunnel has its drawbacks, mainly the prohibitive cost to construct to begin with.  Then you have the water table that's in the area and certain vehicles would not be permitted to use the tunnel.

Johns Pass Bridge In The Movies

In the movie Summer Rental (1985) there is a scene in which the northbound lanes of the Johns Pass Bridge are featured as the family arrives in Florida after a tiring drive from Atlanta.  If you have watched this movie you will also get a glimpse of what the southbound lanes of the Johns Pass Bridge looked like, as Summer Rental was filmed 20+ years before work on the replacement Johns Pass bridges began.  (Believe me, driving from Atlanta to Tampa on Interstate 75 and vice versa is a grueling eight-hour-at-least drive; the other option is to fly and have to navigate Atlanta's Hartsfield International Airport and pay the high air fares!)

Approaching the Johns Pass Bridge

Notice how the northbound span is presently being used to carry two way traffic while the southbound span of the Johns Pass Bridge is being replaced.

View of Johns Pass Bridge construction

We see that the new southbound span of the Johns Pass Bridge is beginning to take shape here as seen from the pedestrian walkway of the northbound span.

Temporary traffic signal

This is a temporary drawbridge traffic signal for southbound traffic. The new bridges will have permanent traffic signals.

Approaching the center span

Here's a view of the old and new Johns Pass Bridge as we approach the center span. Notice that some of the steel bridge parts have been installed.

Steel grid decking

Here is the steel grid deck on the current northbound span of the Johns Pass Bridge. I am not sure if the new bridges will be concrete all the way across like the Treasure Island Causeway or will it be another steel grid deck as before.

Bridge tender's house

This is the bridge tender's house on the current Johns Pass Bridge, which is designed like the Corey Causeway Bridge as well as a few other Florida DOT bridges. When the new bridges open the bridge tender's house will be moved to the opposite side of the bridge offering a great view of motorists, boaters and the Gulf of Mexico.

Artists' rendition of the new Johns Pass Bridge

This was posted on the door to the bridge tender's house and it shows what the new Johns Pass Bridge will look like when it's all said and done. Believe me, we have to go through some inconvenience but in the end it will be a better bridge for you and I.

Looking towards Treasure Island

This is the current northbound span of the Johns Pass Bridge carrying two-way traffic as we descend into Treasure Island. Notice that the girders for the new bridge are already in place.

Closeup view of construction

This is a closeup view of construction on the new span of the Johns Pass Bridge as seen from the pedestrian sidewalk. (Through the magic of the zoom feature of my digital camera, of course).

Steel section of the new Johns Pass Bridge

Here is a newly installed steel section as seen from the pedestrian walkway. I am not sure if this is a movable part or not.

Closeup of the steel section

Here is a closeup of the steel section of the new Johns Pass Bridge. I think this may have something to do with the movable bridge mechanism but I am not sure. After all, this was taken from the publicly accessible pedestrian sidewalk on the northbound span.

South end of Johns Pass

You can see the many restaurants that have sprouted on the Treasure Island side of Johns Pass.

North end of Johns Pass

Here you can see the Johns Pass Village and Boardwalk just across Johns Pass on the Madeira Beach side. Notice the SunCruz Casino ship docked at the village.

Drawbridge traffic signal

This is the traffic signal mounted on a mast arm which was built when the 1971 bridges were upgraded not too long ago. The traffic signals are green but turn red when the bridge has to go up to let a boat through. It will probably be taken down when work begins on the replacement northbound span.

Another view looking north

You can see the gates in the foreground and the construction cranes in the background.

More steel grid decking

This is the steel grid deck of the Johns Pass Bridge looking north. Notice the heavy use of the Johns Pass Bridge from day one back in 1971.

Center of the movable spans

The line that separates the steel plate from the steel grid on the pedestrian walkway is where the bridge opens up. Additionally, the steel plate is a hatch for the locking mechanism as the bridge leaves must be locked before traffic is allowed on the bridge.

Counterweight section

Here we see the section of concrete grid deck (between the steel grid deck and the solid concrete pavement) that goes down into the pit below when the bridge is raised. Further below on the solid concrete deck is the counterweights responsible for balancing the bascule bridge leaves.

Looking north towards Madeira Beach

Here we see the various condominiums that dot the landscape of Madeira Beach as we make our northbound landfall on the Johns Pass Bridge.

Drawbridge gates

Like all other drawbridges, gates are of the railroad crossing type. The lights on top blink when the gates are lowered. Additionally, a bell rings when the gates are lowered or raised.

On the northern shore of Johns Pass

Looking north on Gulf Blvd. we see the newly constructed additions to Johns Pass Village to the right. Believe me, Gulf Blvd. is two-lane while the construction on the new bridges are taking place; however, we'll have a newer Johns Pass Bridge when it's all said and done.

1971 inscription

The 1971 inscription is when the twin Johns Pass bridges opened for traffic replacing an older low-level drawbridge to the east.

Tugboat at the bridge

This is a tugboat which is probably related to the construction activities going on at the bridge. I presume it's parked there for the night.

Sunset and bridge construction

Sunset on Johns Pass while construction progresses on the southbound span.

Looking north on the Treasure Island side

This is a 2006 photo I took of the Johns Pass Bridge heading north from Treasure Island as construction was getting underway on the southbound span.

Another view northbound

Here's another 2006 view of the Johns Pass Bridge with the bridge tender's house to the right as we approach the steel grid deck of the center span.

Draw Bridge Ahead

The standard warning sign for motorists approaching a drawbridge. The font used in this sign is FHWA Series B which was the standard a long time ago. Current Florida DOT standards today call for the use of the FHWA Series C font on Draw Bridge Ahead warning signs. Speaking of fonts, FHWA Series B is taller while FHWA Series C is wider.

Draw Bridge Ahead, Part II

Notice the use of the FHWA Series C font on this warning sign on the southern end of the Johns Pass Bridge facing northbound traffic, different than its counterpart on the northern end of the Johns Pass Bridge.

On the way up!

The mighty steel grid deck of the Johns Pass Bridge as it rises to permit a boat the right of passage.

All the way up!

This is the Johns Pass Bridge in its fully upward steel grid deck glory. As you can see this used to be the northbound span but it temporarily carries two way traffic while the replacement southbound span (together with a new bridge tender tower) is under construction.

Johns Pass Bridge Transition:  Old 1971 Span to New 2008 Span

The next set of photos documents the transition of the Johns Pass Bridge as the replacement southbound span is completed and opened to temporary two way traffic on 18 September 2008.  The 1971 Johns Pass Bridge northbound span - which has served the needs of both motorists and boaters both in Treasure Island and Madeira Beach for 37 years along with its southbound counterpart (which was torn down to make way for the new southbound span) - is scheduled to be torn down in order to make way for the new northbound span which will be identical to the newly built southbound span.

 

Looking south on the new southbound span

In the background you can see the decks being added to the new movable span.

Closeup of the new movable span

Seen from the 1971 northbound span, the decks are being added to the moveable span in pieces. Notice that the new movable span must be kept raised as not to impede boat traffic, as Johns Pass sees plenty daily.

Closeup view of the new moveable span

Also seen from the old 1971 northbound span, it's a lot taller!

Housing for the new moveable southbound span

This is where the bottom part goes into a pit when the bridge is raised. Another feature is that the moveable span will be concrete just like the Treasure Island Causeway.

Another view of the new moveable southbound span

This is seen from the northbound span looking north as the decks are being set into place.

This is looking north on the northbound span as seen from the safety gate.

And now, the northern leaf of the moveable southbound span

All the decks are installed on the northern leaf, ready for the concrete pour to follow.

A Johns Pass southbound span almost done!

All the concrete is poured onto the moveable span leaves; all there is to do is the required electrical and other work to put the bridge into service.

View of the new southbound span - almost done!

This is the all concrete southbound span as seen from the Madeira Beach side.

Another view of the old and new

The new southbound span with all the signs and gates installed as seen from the northbound span.

Another view of the new southbound span

There will be a major difference when you cross the Johns Pass Bridge: No more having to listen to the drone sound of the steel grid deck like you used to with the northbound span.

Another view of the completed southbolund span

This is looking north on the northbound span.

The new southbound span in the closed down view

Looking from the Madeira Beach side, this is a view of the new Johns Pass southbound span in the closed down position for the first time. Notice how wider and taller the southbound span is than its 1971 northbound counterpart.

We're almost there!

Another view of the southbound span with the striping to accommodate the temporary two way traffic while the adjacent northbound span gets replaced.

Another view of the new southbound span

Here's another view of the new southbound span in the closed down mode as seen from the northbound span.

Temporary piers are set in place

This is needed so that the cranes can disassemble the old 1971 northbound span and assemble the new northbound span.

Where's the Draw Bridge Ahead sign?

It got moved to the entrance of the new southbound span of the Johns Pass Bridge and it has a yellow beacon on top! Florida DOT standards call for a yellow diamond Draw Bridge Ahead warning sign to be mounted with a yellow flashing beacon on top, which is activated when the bridge is being raised. The contractor moved the sign from its former home just up the road on Gulf Blvd. as the new southbound Johns Pass bridge was opened.

A new Johns Pass southbound span in operation

The new southbound span is now in service, ready to serve the needs of motorists and boaters for many years to come. To the left is the old northbound span with the steel grid deck raised in preparation for eventual demolition.

Get up close and personal with a drawbridge

A feature of the new Johns Pass Bridge is the new observation decks on either side of the movable spans. You can watch the drawbridge up close as it is being raised and lowered; don't worry there is a pedestrian gate so you don't accidentally get on the span when it's being raised or lowered. Believe me, this is a great sight to see as the movable spans are taller than their 1971 counterparts.

A look at the old and new

The new southbound span is a hydraulic lift compared to the old northbound span as seen to the left being a gear lift. Besides, opening and closing the new southbound span takes only a minute compared to the old northbound 1971 span.

Looking south on the new movable span

In the background is the bridge tender house, which I agree is a much better art deco design for the 21st Century than the Air Traffic Control Tower design of the 1971 northbound span. Besides, it's all concrete going across which benefits both motorists and pedestrians - no more driving or walking across the treacherous steel grid deck!

Where the two new southbound span bridge leaves come together

This is much like the new Treasure Island Causeway which features the exact same design.

View of the new bridge tender house

I got to agree; the bridge tenders who work the Johns Pass Bridge now have a new bridge tender house they can be proud of. The bridge tender has a splendid panoramic view of not only Johns Pass Bridge itself but a paonramic view of the Gulf of Mexico and its beautiful sunsets!

Looking south on the new southbound span

This is looking towards Treasure Island on southbound Gulf Boulevard (FL 699). Notice the new lighting fixtures installed as part of the design feature.

Looking north on the new southbound span

The roadway as you will see has an emergency breakdown shoulder much like Interstate 275. Besides, when you drive south it gives you the look and feel of Interstate 275 - unfortunately, this is FL 699 and drawbridges are not allowed on interstate highways, with very few exceptions such as the newly replaced Woodrow Wilson Bridge carrying Interstates 95 and 495 over the Potomac River in Washington, DC.

Ode to the old steel grid deck bridge

As you will see, the steel grid deck of the old northbound span is being prepared for demolition. The old northbound span has been raised to the up position permanently so that the steel grid deck can be dismantled. With the new southbound span of the Johns Pass Bridge now opened, Pinellas County motorists have one less steel grid deck to worry about.

Looking at the new gate assembly on the new southbound span

Like all drawbridges in Pinellas County, drawbridge gates are of the railroad crossing type with red lights on the top that blink when the gates are lowered.

The overhead drawbridge signal

This is the drawbridge traffic signal on the new southbound span with a view of the old steel grid deck of the northbound span in the background. When the steel grid deck of the northbound Johns Pass Bridge is demolished, a part of Johns Pass Bridge will be history.

Source of information for the history of Johns Pass is from the Johns Pass visitor portal site.
