N.W. 36th Bridge Replacement


This contract included two distinct projects. The first (425979-1-52-01) included milling and resurfacing, median modifications, sidewalk, and ADA ramp construction along NW 36th Street. The limits of this project extend west of Lee Drive to east of Coolidge Drive. The second (418065-2-52-01) included major reconstruction including the replacement of the N.W. 36th Street bascule bridge over the Miami Canal. This project also included milling and resurfacing, drainage, lighting, signalization, and minor intersection modifications of NW 36th Street at N.W. South River Drive and NW North River Drive. During this project, the functionally obsolete Hanover Bascule Bridge was replaced with 2 fixed concrete bridges. The existing steel bridge is a single leaf bascule built in the 1950’s and follows an innovative design solution for skewed crossings.


Preserving Civil Engineering History

In the early 1950¹s, the bridge became necessary to accommodate increasing vehicular traffic to/from Miami International Airport and boat traffic on the Miami Canal; it would also replace an antiquated lift bridge from the 1920¹s. The engineering firm of Hardesty & Hanover developed the Hanover Skew bridge design. This design would be able to provide a solution to the skewed crossing over the Miami Canal at N.W. 36th Street. The historical significance of this bridge is highlight by the fact that it was 1 of 3 constructed in Florida and 1 of 4 constructed in the United States; all were constructed between 1945 and 1963.


In the 1970’s the Miami Canal was closed to navigation at N.W. 36th Street and the bascule bridge was no longer operational.


In July 2013, the Miami-based Design-Build Team, of MCM (contractor) and A&P (designer), was awarded the contract to remove and replace the historical bridge. During construction, it was decided that the bridge’s internal machinery should be preserved. After some minor repairs and renovations, the machinery was transported to its final resting place in front of the Florida Department of Transportation Miami Headquarters.
