Drivers eastbound on Interstate 84 near the mouth of Weber Canyon in Morgan County will encounter temporary right-lane closures in the coming months while Questar Pipeline Company (QPC) replaces a section of high-pressure natural gas pipeline on a steep hillside above the highway.
The closures—affecting a two-mile stretch of I-84 from mile marker 89 through mile marker 91 in Weber Canyon–will occur Monday through Friday between 6 a.m. and 3 p.m. and possibly on Sundays from 6 a.m. to 6 p.m. There will be no lane closure on holidays or holiday weekends. The temporary daily lane restrictions will be in effect for the duration of construction on the hillside, which is scheduled to begin May 8, 2014, and end Nov. 15, 2014.
QPC’s traffic-safety plan for construction in Weber Canyon is designed to protect drivers in the unlikely event rock or other debris reaches the road from the hillside above. As an extra precaution, QPC will also install temporary retaining fence and earth berms topped with mesh fencing along the work area above the affected stretch of I-84 to contain dirt and rock disturbed during construction. QPC developed its I-84 traffic safety plan with the cooperation of Utah Department of Transportation, which has approved the plan.
QPC’s work in Weber Canyon is part of a multi-year project to upgrade a vital segment of the company’s system known as Main Line 3. Originally built in 1929 and replaced in the 1960s, ML 3 runs from Coalville to South Weber and supplies natural gas used in thousands of Wasatch Front homes and businesses. QPC has been replacing ML 3 in phases since 2009 and so far has installed just over 23 miles of new, stronger pipe. This summer, QPC will replace 3.3 miles of pipe. A final 1.5-mile segment will be replaced in 2015.
