State Route 95 Cottonwood Wash Bridge Replacement
State Route 95 Cottonwood Wash Bridge Replacement
Project Overview
The Utah Department of Transportation (UDOT) has begun building a new bridge on State Route 95 (SR-95) over Cottonwood Wash in San Juan County, Utah. The road will be reduced to one lane with temporary signals directing one-way traffic. Motorists are required to wait until green for their turn to proceed. Motorists can expect delays of 10 minutes or more from 7 a.m. to 6 p.m. Monday - Thursday, and from 7 a.m. to 5 p.m. on Friday. A wide load restriction is in place for over 11 feet wide.
The new bridge will replace the aging bridge, accommodate local and tourist traffic, and address large storm events that result in large volumes of water passing through Cottonwood Wash. Work will include the removal and replacement of asphalt on both sides of the new bridge to tie-in and make a smoother ride.
The project is expected to continue throughout the summer. Please sign up for the latest project updates from the information below.
Project Updates
Crews are continuing installation of the bridge support structure and have begun forming the edge of the bridge deck in preparation for the next phase of work.
As soon as Monday, August 5, crews will begin the deck pour for the south half of the bridge. This important night work may lead to significant travel delays of approximately 15 minutes.

Background: Emergency Bridge Repair
A routine general inspection of the bridge on August 2, 2021 revealed potential issues with erosion, prompting further evaluation of the site by a structural engineering team. UDOT closed the bridge and a structural evaluation team determined the collapse of sandstone at the footing of the east abutment was significant enough to close the bridge for public safety while UDOT pursued an emergency repair to the structure. Engineers say it appears high flows in the wash during flash flooding scoured a lower layer of rock away, leaving the upper layer of rock unsupported. The bridge spans approximately 110 feet and was built in 1959.
The bridge reopened October 28, 2021 after temporary repairs were made.
