Tree branches hanging into bicyclist's head space

On the Washington Avenue bike lane (just west of San Carlos), there are tree branches hanging into a space where a bicyclist's head (and eyes!) might be. In order to prevent the branches from hitting my head, it's necessary to move out of the bike lane.
