Eyes on the Street: Why Agencies Need to Warn Bike Riders of Construction

5:19 PM PST on November 18, 2013

When street pavement gets torn up during construction, people on bicycles need fair warning, or else they'll be in danger.

Daniel Erat sent in the above video he filmed on his bike commute on Golden Gate Avenue. At the Steiner Street intersection, he and another rider hit a patch of roadway where the asphalt had been removed for a construction project, busting his wheel and knocking the woman off her bike:

My front tube popped as soon as I hit the spot where the asphalt resumed, and while pulling over, I heard a noise behind me and saw that another cyclist had fallen in the road at the same spot (I think she was uninjured but pretty shaken up; she walked away)...
There's a sudden 1" lip where the asphalt begins at the east side of the intersection, and the spot is at the bottom of a hill where cyclists are likely to be moving quickly and to have most of their weight on their front wheels. I'm concerned that the spot has a high potential for damaging more bikes (my front hub is loose now and my handlebars got misaligned) and for injuring cyclists -- it's a popular commuting route to get downtown.

Had a driver been behind the woman when she fell, the situation could have led to serious injuries or worse.

It's unclear who's managing this construction -- most commonly, it seems to be done by the Department of Public Works, the SF Public Utilities Commission, PG&E, or a contracting company. Erat said he phoned the problem in to 311, but the staff "apparently sees this as less urgent of an issue than I do."
