Over the course of the project, the entire 1,785-foot long elevated Bronx approach to the bridge will be replaced from the ground up with a completely new structure, including foundations and 15 double-arch concrete piers to support a widened roadway constructed of steel girders and concrete deck, according to the release. The new structure will be wider to provide lanes and shoulders that meet present-day width standards, although the number of travel lanes on the Bronx approach will remain the same: three in each direction.

The initial stage of the Bronx approach project involves constructing the new piers and foundations, and removing the median barrier. That work will last approximately a year-and-a-half, beginning by year's end, according to the release.

The second major stage of the project will entail demolition of the existing roadway, lane by lane, and constructing the new roadway superstructure over the course of two-and-a-half years. The third major stage, which is expected to be completed over the final four months of the project, will involve demolishing the existing piers and final site improvements such as landscaping and draining upgrades.
