SMITHFIELD, Cache County — Road work will begin next week on U.S. 91 between Smithfield and the Idaho state line.

The work begins Tuesday and will include a chip seal across all four lanes of the roadway, which was completely reconstructed in 2007. The “chips” used in a chip seal are small pea-sized rocks that are applied to the roadway with an asphalt emulsion. Once the chips are rolled into the asphalt with heavy equipment, vehicles are allowed to drive on it.

Work is expected to be completed in mid- to late July. Construction will take place weekdays from 7 a.m. and 7 p.m. Occasional Saturday work may be necessary.

Comment on this story

Motorists are reminded to reduce their speed significantly once the chips are initially applied, Utah Department of Transportation officials said as the small rocks can easily be dislodged and fly up and damage windshields.

Crews will keep one lane of traffic open in each direction, except at the areas of traffic signals. Flaggers will be present, and motorists are expected to follow their directions when in the zones where work is being performed.
