How much will it cost to build bicycle and pedestrian paths on the Verrazano Bridge? A lot less than the MTA says it will, if the agency removes unnecessary ramps from the project, according to advocates and engineers who’ve reviewed the options.
Last year, the MTA and engineering firm Parsons Brinckerhoff released a preliminary cost estimate of $300 to $400 million for the bridge paths [PDF]. It was a steeper price than advocates with the Harbor Ring Committee, which has built momentum for the car-free paths, had been expecting. Back in 1997, engineering firm Amman & Whitney had pegged the cost at $50-60 million (in 2016 dollars).
In an interview published yesterday on Urban Omnibus, Harbor Ring Committee chair Paul Gertner attributed the MTA’s high pricetag to the design for the Brooklyn approach, which includes elaborate ramps connecting to the Shore Parkway Greenway. It’s not clear how much the ramp system adds to the MTA’s cost estimate, but the structures would be substantial, with concrete columns supporting a winding bikeway that touches down on the greenway.
“As far as we can tell, [Parsons Brinckerhoff] started with the assumption that it had to start at the waterfront greenway, and then proceeded to design this huge ramp system,” Gertner said.
A greenway landing isn’t worth the extra cost, Gertner told Streetsblog, since it would compel anyone who’s not planning to use the greenway to take a long detour. In the Amman & Whitney plan, the path touched down at 92nd Street by Fourth Avenue, a much more direct connection to the street network.
