TREMONTON — The transportation department says a project to fix bridges near the Interstate 15/84 split in Tremonton will be more difficult and costly than originally planned.
And with the increased workload, northbound freeway travelers should be prepared for traffic.
In early-April, work began on a bridge restoration project on I-84 between Snowville and Howell. As part of the project, the Utah Department of Transportation is removing existing asphalt, doing pothole repairs and resurfacing bridge decks in the area. Traffic has been reduced to one lane on I-84 through work zones, with temporary traffic signals in place on some freeway overpasses.
A recent inspection revealed that the bridge decks in the area have deteriorated more than the state previously thought. Ivan Hartle, UDOT‘s director of financial programming, said additional “hydro demolitions” are needed on several of the bridge structures. A hydro demolition is a process where high pressure water is used to remove deteriorating concrete or asphalt.
UDOT originally planned to do hydro demolitions on two bridges in the area, but Hartle said the state has added eight more. As a result, UDOT requested an additional $2.4 million be added to the project. The Utah Transportation Commission approved the funding request on May 17, bringing he project’s total value to $6.4 million.
Hartle said the new work will change UDOT’s plans for traffic maintenance, meaning there will be more impacts to commuters using the freeway.
UDOT is also busy on a portion of I-84 further south.
In his weekly construction report, UDOT Region One spokesman Vic Saunders said work is progressing on a pavement preservation project on I-84, from Riverdale Road to U.S. 89.
As part of that project, crews are replacing sections of concrete pavement and replacing the asphalt shoulders. Work is expected to occur in the Uintah and South Weber area, as well as near Riverdale Road between 7 a.m. to 5 p.m., Saunders said. One lane will remain open in each direction as work is ongoing. Ramp closures from I-84 to Adams Avenue Parkway and bridge work on the parkway are expected to take place on May 31 through June 3.
Both project are scheduled to be finished sometime in the summer.
