Transportation Commissioner Polly Trottenberg says the Department's "Bikes on Bridges" campaign will look for ways city bridges can accommodate more bikes and boost safety.

The proposal will be announced at a City Council hearing Thursday afternoon.

Trottenberg said the study will focus on the 16 bridges connecting northern Manhattan and the Bronx. "That's one area where I really heard loud and clear people wanted to get improved cycling experience over the Harlem River," she said.

The recommendations will be incorporated into improvements on the bridges, possibly as soon as next year, and guide future bridge rehabilitation capital investments.

The DOT is also in preliminary stages of discussing a partnership with the MTA to pilot a project to put racks on buses to carry bikes over bridges where bike access is the worst.
