Based on initial indications, the U.S. 1 mainline bridge over Highland Avenue and the bridge carrying Route 413 (Pine Street) over U.S. 1 will be staged construction.
The West Interchange Road bridge and the Corncrib Lane bridge will most likely be replaced using detours. With the lower volumes of traffic, the contractor can demolish and reconstruct the bridges faster than a staged construction.
This is still under analysis.
