JACKSON, Wyo. (KIFI) – The Wyoming Department of Transportation (WYDOT), together with contract crews from Ames Construction, will briefly change the Snake River channel on the Snake River Bridge.
If you propose to drift the river underneath the bridge within the subsequent six months, please be suggested of this transformation.
The minor channel change is the most secure technique for river customers and essentially the most hydraulically light solution to preserve the movement of the river.
Over the summer season, WYDOT consulted with Teton County, Protect Our Water Jackson Hole, Snake River Fund, Rendezvous Park, adjoining landowners, and others to establish one of the simplest ways to do that. Because the quantity of water launched from Jackson Dam has been lowered to its winter movement, it was determined that this time of yr is greatest to reduce affect on the river.
Construction has progressed on the 2 piers on the west facet of the Snake River the place there isn’t a movement. After altering the channel, Ames will begin work on piers 3 and 4 on the east facet, that are at the moment within the present channels of the Snake River. A cofferdam shall be constructed across the work zone to create a dry workspace for the contractor, and the channel shall be briefly modified to movement between piers 2 and three.
WYDOT and Ames will restore flows to the unique channel within the spring earlier than excessive water season. This change will have to be made once more subsequent fall for the second stage of the bridge development and shall be eliminated once more within the spring of 2025.
Additionally, as a part of the settlement with Rendezvous Park, WYDOT is working with the contractor to create wetlands within the park to offset the wetlands that shall be eliminated alongside the roadway as a result of development. This work started Oct. 4 and can proceed by the late fall, when native park use is low and can happen in two places close to the undertaking.
The work is a part of the Snake River Bridge and Intersection undertaking, which was awarded in November of 2022. The work consists of the alternative of the Snake River Bridge on WYO 22, the reconstruction of
the intersection of WYO 22 and WYO 390, wildlife crossings and different work on roughly 1.80 miles of WYO 22 & WYO 390 in Teton County. More details about the undertaking historical past is available HERE. The completion date for this undertaking is June 30, 2025.
