LKB performed construction inspection on this project to replace the deteriorated Crane Road Bridge carrying the Bronx River Parkway over the Bronx River and the adjacent bridge over the Metro-North Railroad. Also known as the historic “mushroom bridge”, this bridge’s architectural details include circular concrete piers, covered with rustic stone that resemble a clutch of “mushrooms.” A steel core and bracket design was utilized to keep the mushroom shape, finished with salvaged architectural stone, ensuring the replacement bridge resembled the original design.
The original bridge, built in 1924, continued to be operational during most of the project while the new bridge was constructed alongside it. Both vehicular and railroad traffic were maintained by several complex detours throughout the term of the project.
To improve traffic operations and safety, the project widened the travel lanes and shoulders, by increasing the overall bridge width. Acceleration/deceleration lanes to Crane Road were increased and the curve alignment was adjusted to improve sight distance. New sidewalks were also added to enhance pedestrian access to the Bronx River Parkway reservation, and the southbound Metro-North platform was reconstructed.
