The city has resumed work on a controversial bike boulevard in Brooklyn after a nearly six-month delay, officials said Thursday.  

The Department of Transportation began carrying out prep work along the Underhill Avenue bike boulevard corridor in Prospect Heights Wednesday night, the agency said.

Construction of the redesign, which spans eight blocks of Underhill Avenue, initially began this past summer, but was paused in the fall after the city faced backlash from some local residents and business owners who claimed their voices were not being heard.

One business owner in January told NY1 the unfinished project was hurting her business, calling it “poorly thought out” and saying the city had eliminated nearby parking spots.

The redesign was intended to calm traffic in the area, which includes an elementary school and a playground. The DOT said additional community outreach was conducted during the pause, and that locals are supportive of the project.

“Following a thorough community engagement process, it is clear the community strongly supports this work on Underhill Avenue, which will better protect everyone on the corridor — whether you’re biking, driving, or walking,” DOT press secretary Vincent Barone said in a statement.

Most of the remaining work on the bike boulevard, which is almost finished, is expected to wrap up in the coming days, so long as weather permits, the DOT said. Final touches will be completed in the spring, it added.

The Prospect Heights Neighborhood Development Council, a neighborhood advocacy organization, released a statement Thursday lauding the DOT’s decision to resume the project.

“Public space revisionings like the Underhill Avenue Bike Boulevard contribute to creating safe, sustainable and equitable public spaces, and we’re relieved that Mayor Adams plans to complete these improvements instead of rolling them back,” the chair of the Council, Gib Veconi, said in a statement.
