Construction of a pedestrian overpass over I-15 in Farmington will disrupt traffic on the freeway for several weeks this fall. Work on the State Street overpass will begin in late August or September, according to county public works director Sid Smith.
Low bid on the overpass, being built with a combination of federal, state and local funds, is $969,963, Smith said, which is about 10 percent over what the design engineer estimated.The contractor anticipates working around the clock, seven days a week, to minimize traffic disruptions, Smith said, which means the job will require a flagman 24 hours a day. That stipulation increases the project's cost by $40,000 to $50,000, Smith said.
To minimize traffic disruptions, the freeway lanes will be closed between midnight and 6 a.m., Smith said, and traffic will be routed around the construction site through Farmington.
The pedestrian overpass will span I-15, the frontage road, and the Union Pacific tracks, making it one of the longest such structures in the state, Smith said.
