Road work that has restricted traffic on I-15 between Lehi and the Point of the Mountain will likely continue beyond the original Oct. 22 completion target.

Two shipments of sealant for the road rehabilitation project were determined to be below contract specifications, forcing a delay in work, said Utah Transportation Department spokesman Kevin Beckstrom.The work has caused lane restrictions on the approximately 5-mile stretch of I-15 since late March, with the three northbound lanes closed and all traffic diverted onto southbound lanes, Beckstrom said.

Project engineers Tuesday said the lanes would continue to be closed until Aug. 12, when traffic will be switched to the northbound lanes and the south side of the freeway closed, he said.
