The streets have been repaved. Lane striping, crosswalks, and stop bars have been added back. But there’s something missing from two streets in DOT’s bike network: bike lanes.

In Williamsburg, Driggs Avenue has been repaved — but you would never know it’s a key bike connection from the Williamsburg Bridge. The street has all its stripes back except the bike lane markings.

In Lower Manhattan, Lafayette Street between Canal and Chambers was also recently repaved. Markings were added back, but so far not the buffered bike lane. Instead, many motorists are now using what should be the bike lane space as a driving lane.

DOT did not respond to a query about why the bike lanes are taking longer to paint than the rest of the street markings.

Lafayette Street, which feeds directly to the Brooklyn Bridge path and is lined with Citi Bike stations, is wide enough for a protected bike lane. North of Prince Street, Lafayette already has a protected lane: When DOT repaved that section last year, it upgraded the bike lane. DOT said it didn’t take advantage of this year’s repaving to upgrade the other section of Lafayette because it would have had to go before the community board for a significant street redesign.

It seems DOT has limited how much it uses road resurfacing to improve street design and safety. Converting a striped bike lane into a buffered bike lane? Easy. Converting a buffered bike lane into a protected bike lane? Apparently that’s too tough.
