A crumbling section of the Brooklyn Queens Expressway that has long plagued New York City is expected to be repaired beginning in 2030.

NYC Mayor Zohran Mamdani announced a plan to address the highway’s cantilever section over Brooklyn Heights that would require the installation of a temporary highway through the northern Brooklyn neighborhood, according to a press release from the Mayor’s Office.

The temporary structure—a two-level highway bypass above Furman Street and below the promenade between Atlantic Avenue and Columbia Heights—would allow the continued passage of the highway’s more than 130,000 daily users, while retaining access to the Brooklyn Heights Promenade and Brooklyn Bridge Park.

City Transportation Commissioner Michael Flynn reported to Gothamist that sections of the promenade would require closure throughout construction but pledged to always keep a portion of the park open.

The temporary highway would be tucked out of view from the promenade.

A second temporary, elevated structure is also expected to be constructed from Columbia Heights over the Brooklyn Bridge approach to the Manhattan Bridge, according to the mayor’s press release.

The crumbling section of the BQE between Atlantic Avenue and Sands Street is owned by the city and is now 20 years past its design life. It has served as a point of contention for the two previous mayoral administrations, whose plans to rehabilitate the section never got off the ground, Gothamist reported.

The 10-year rehabilitation plan is scheduled to launch in 2030 with the construction of the temporary highway structure, with plans to begin repairing the triple cantilever in 2032. If all goes to plan, the temporary structure will be torn down and the restored highway will open to traffic in 2040.

Repair work will include replacing deck joints, concrete and rebar, as well as improving drainage, railings and lighting to extend the highway’s service life by 40 years.
