SUPPLEMENTARY INFORMATION:

The Union Pacific Railroad Company has requested a temporary change to the operation of the Union Pacific Railroad Drawbridge, over the Carquinez Strait, mile 7.0, at Martinez, CA. The drawbridge navigation span provides a vertical clearance of 70 feet above Mean High Water in the closed-to-navigation position. The draw operates as required by 33 CFR 117.5. Navigation on the waterway is commercial and recreational.

The drawspan will be secured in the closed-to-navigation position from 10 a.m. to 4 p.m. on August 23, 2017, to allow the bridge owner to conduct emergency repairs. This temporary deviation has been coordinated with the waterway users. No objections to the proposed temporary deviation were raised.

Vessels able to pass through the bridge in the closed position may do so at any time. The bridge will not be able to open for emergencies and there is no immediate alternate route for vessels to pass. The Coast Guard will also inform the users of the waterway through our Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so that vessel operators can arrange their transits to minimize any impact caused by the temporary deviation.

In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the effective period of this temporary deviation. This deviation from the operating regulations is authorized under 33 CFR 117.35.
