WASHINGTON – GRAYS HARBOR – ABERDEEN – Bridge Notice
WSDOT will be inspecting the Chehalis River Bridge (US-101) (LLNR 15897) at Chehalis River mile 0.1, at Aberdeen, WA. The inspection will take place between 0800 and 1500 on 07 – 10 Mar 2022. The bridge will be inspected using an under-bridge inspection truck (UBIT) that occupies a portion of the roadway and extends a boom under the bridge. No impact to the navigational clearance will occur. The vertical clearance will temporarily be reduced with the UBIT bucket, but the UBIT will give way to tall marine vessels. Mariners are advised to use caution while transiting the area. UBIT bucket will display a flashing amber light on the bottom and a safety lookout will be on the bridge. Bridge openings will occur as usual. For additional information, contact Ryan Collins, P.E. at (564) 200-2085 or firstname.lastname@example.org
WASHINGTON – PUGET SOUND – SEATTLE TO BREMERTON – DUWAMISH WATERWAY – Bridge deviation
The Coast Guard has approved a temporary deviation for the Spokane Street Bridge (LLNR 16870.1) across the Duwamish Waterway, mile 0.3, in Seattle, WA, for 29 Jan – 01 Feb 2022. The period for this temporary deviation is for the east half of the draw closure from 2359 on 28 Jan to 0500 on 01 Feb 2022. This deviation supports equipment upgrades for the swing turret. The deviation authorizes the subject bridge to open the west half of the swing span to marine vessels. Vessels able to pass through the subject bridge in the closed-to-navigation position may do so at any time. The Spokane Street Bridge provides 55 ft. center, 44 ft. east-west side of vertical clearance and 250 ft. of horizontal clearance in the closed-to-navigation position. While the west half of the draw is open, the bridge provides unlimited vertical clearance and 110 ft. of horizontal clearance. Vertical and horizontal clearances are referenced to mean high-water elevation. No alternate route is available on the Duwamish Waterway. 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. For additional information, contact Matthew Donahue at (206) 684-5301, or email@example.com.
