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.”
