OGDEN -- Ogden Canyon will be completely closed every night for the next three months.
As the city continues repair work on a century-old water pipeline that runs through the canyon, full-night closures of State Road 39 through the canyon will begin Wednesday.
Utah Department of Transportation spokesman Vic Saunders said the canyon will close at 8 p.m. Sunday through Thursday to all but canyon residents. The canyon will reopen at 5 a.m. the following morning.
On Friday and Saturday, the canyon will be closed from 9 p.m. to 6 a.m. the next morning.
Saunders said the nighttime closures are necessary to accelerate the work on the pipeline.
During the daytime hours, the use of the traffic signals to move traffic through the canyon in the limited space available will continue, Saunders said.
Motorists should expect that traffic will be impacted and heavy congestion is expected most of the time, particularly in the morning hours.
"Those with time-sensitive travel should plan now to use alternate routes to avoid significant delays," Saunders said.
The city hired Brigham City-based Whitaker Construction for the project, which is expected to wrap up by the beginning of April.
The 24-inch pipeline, nearly 100 years old, winds through Ogden Canyon and carries water from Pineview Reservoir to thousands of Ogden residents.
City officials say it's a major water supply line to the city, but it's in poor condition, and repairs just can't be put off any longer.
The project will cost $8 million. The city will issue $4 million in bonds to pay part of the costs. The state drinking water board has agreed to purchase the bonds for $4 million at an interest rate of 2.6 percent for a term of 20 years.
The Utah Division of Drinking Water had previously committed $4 million.
