Following a federally-mandated review of the transportation mitigation plans, for the pending L train shutdown next year, the MTA will discuss those and other concerns at a public meeting Monday night at MTA headquarters from 5-8 p.m.

The Federal Transit Administration reviewed how the MTA's plans for increased bus service over the Williamsburg Bridge, new ferry routes and bike lanes will affect the city and the environment.

Some of the reports findings were not a surprise. The FTA wrote that running 70 buses an hour over the Williamsburg will impact the entrances and exits to the bridge. "Noise levels may increase along 14th Street and the approaches to the Williamsburg Bridge, but the increase would be temporary for the duration of the tunnel closure and is not considered a significant adverse impact."

But contrary to some concerns from business owners on 14th street, the report found the new bike lanes and walkways could actually benefit commerce.

"Along the 14th Street corridor, the temporary SBS service and additional pedestrian space and bike lanes would enhance mobility benefiting existing businesses with easier access to customers," the report found.

The advocacy group the L Train Coalition wrote in a statement that the MTA's plan has "many good elements," but could be improved. "We believe the four bus lines and the HOV3 lanes are important but we are concerned about the effects on air quality. We also feel that they are underutilizing ferries and had they planned more the waterways could have been a more important part of the plan. We also welcome the additional G train cars and added service."

The MTA wrote in a statement that there will be more public meetings to come.
