NORTH OGDEN -- The project to fix the North Ogden Divide will cost more money and last about a month and a half longer than originally expected because safety problems must be corrected.
Officials with Weber County's engineering department say the divide will remain closed until Aug. 15 so crews can repair rock falls and work on ground-stability issues.
After being delayed last year because of a funding shortage, the project began in early June and was expected to wrap up earlier this month.
As part of the project, crews are replacing an existing concrete barrier with a guardrail, widening the road and straightening some curves over a 700-foot section on the east side of the divide.
New signs and striping also are planned for the same section, as well as rock scaling to remove any loose rocks that could fall onto the road.
Mike Tuttle, of the county engineering department, said geotechnical engineers found some unstable soil under the new retaining walls, a problem that wasn't seen during the investigative borings and design phase.
The engineers also noticed some hanging rock they felt created significant safety hazards.
Tuttle said both items are in the process of being repaired.
According to the Statewide Transportation Improvement Program, the total cost of the project at its original scope was $643,569.
Weber County anticipates the additional work will cost approximately $120,000.
"We are very sensitive to the needs of those this closure affects, and we are doing everything we can to ensure we reopen the divide as quickly and safely as possible," Tuttle said.
"Our No. 1 concern is in protecting everyone that uses this corridor."
The project is a Weber County endeavor, but the Utah Department of Transportation is overseeing it, because funding came from the Federal Highway Administration.
