I came back the other direction (southbound) on this same stretch last night, and the Pipe Spy crew had packed up for the evening but left a metal plate in the bike lane to cover the hole they were working on until they returned. This plate was hard to see in the dark, and had a sharp, rather tall edge which could easily cause a crash or at least a flat tire if a bicyclist rolled over it unaware.

Usually when crews leave out metal plates like this, especially on bike routes, they soften the edge with some asphalt to protect road users, especially bicyclists, who roll over it.

Again, please follow up with Pipe Spy to encourage them to increase their safety protocol and traffic mitigation standards for the work they are doing around Emeryville.
