West Fargo Interchange (Exit 343) Bridge Deck Overlay & Abutment Repair
The bridge is located over I-94 at mile 343.803. The bridge carries West Fargo Main Avenue traffic over I-94 toward the eastbound onramp loop and also exiting eastbound I-94 traffic over I-94 towards West Fargo Main Avenue.
This project is scheduled for the April 13, 2018 bid opening. Construction activities could possibly begin in May of 2018. It is anticipated that this project would take a maximum of 4 months to complete.
The estimated cost of the project is $1,035,000.
Need for Project
- The west abutment has moved causing the top portion of the abutment wings to break.
- The west end of the deck is deteriorating and full depth holes have formed in the deck.
- The west end of the deck is delaminated. If left untreated, the bridge deck is susceptible to spalling, which is when the top layer of the deck concrete becomes loose.
Description of Work
Approximately 5 feet of the west end of the deck will be removed full depth and replaced. The entire deck will be milled and overlaid with concrete. The west abutment will be repaired. The west approach slab will be replaced and an expansion joint will be installed.
Eastbound and westbound I-94 traffic will be maintained through the interchange construction zone during construction. The bridge will be limited to one-lane traffic during construction with the bridge remaining open for exiting eastbound I-94 to Main Avenue traffic. The bridge will be closed during construction for West Fargo Main Avenue traffic wishing to use the eastbound I-94 onramp loop. Main Avenue to eastbound I-94 traffic will instead be detoured to travel west on I-94 to Exit 342 (Raymond Interchange) and return east on I-94. The length of this detour is 2.47 miles
