The two-way lane runs from the Williamsburg Bridge for a quarter of a mile along Delancey Street.
“We are doing critical work now to help mitigate New Yorkers’ pain during the L train repairs,” said Mayor Bill de Blasio. “We look forward to welcoming thousands of daily cyclists to the new protected bike lane down Delancey Street, which will be a key link in our transportation network when the L train tunnel shuts down.”
More bike riders use the Williamsburg Bridge than any other East River crossing: An estimated 7,300 every day.
The city expects that when the L line shuts down next year for 15 months, the number of bike riders could triple.
