Drawbridge Operation Regulation; China Basin, Mission Creek, San Francisco, CA

The Coast Guard proposes to temporarily modify the operating schedule that governs the 3rd Street Bridge, across China Basin, Mission Creek, mile 0.0, at San Francisco, California. This action is necessary to allow the bridge owner, the City of San Francisco, to keep the drawspan in the closed-to-navigation position in order to conduct critical mechanical and structural rehabilitation over an estimated 18 month period, scheduled to commence in February 2018. The temporary change to the regulations is expected to meet the reasonable needs of navigation on the waterway. We invite your comments on this proposed rulemaking.
