Bridge repair at the I-90/US16 Interchange in Buffalo requiring short term road closure

Buffalo, Wyo – The Wyoming Department of Transportation and its contractor S&S Builders, LLC have begun work to repair damages to a bridge on I-90 in Buffalo. 

The bridge was damaged in July of 2021 when a high-profile truck traveling southbound on US 14/16 struck a portion of the I-90 Bridge causing damage to the structure.  The damage to the bridge resulted in needing to close the driving lane of the eastbound lane of I-90 at mile marker 58.65.

The extent of the damage included a portion of the bent cap being broken off, and severe damage to the outside girder – a primary support system of the bridge. Upon inspection, it was determined the passing lane of the bridge structure was sound and allowed for traffic to be detoured to the passing lane.

S&S Builders, LLC has been doing preliminary work this past week in preparation for repairing the bent cap and replacing the girder.  Removal of the girder will require the contractor to temporarily close US 14/16 on Thursday, September 1 to remove the girder.   The new girder will be replaced within a few weeks’ time and will require another short-term road closure at that time.

The closures are scheduled to run from 9 a.m. to 3 p.m.

A detour will be put in place and includes the following.

Eastbound traffic from US 14/16 West wanting to access US 14/16 East will be detoured to I-90 East to the Red Hills Road Interchange Exit 63, cross under the interstate and access I-90 West to Exit 58.

Westbound traffic from US 14/16 will be detoured onto I-90 West to Exit 57 onto I-25 to Exit 299 onto Hart Street.  Detour signs will be in place throughout the project area.  

Motorists are asked to plan their travels accordingly. 

The bridge repairs are scheduled to be completed by October 31, 2022.
