Twin Falls, Idaho (KMVT-TV) Work is expected to begin Monday August 6 to seal coat U.S. 93 west from north Twin Falls to its junction with U.S. 30.
Traffic will be reduced to one lane in each direction as crews work to apply the seal coat to the new section of roadway beginning just north of the U.S. 93/U.S. 30 junction west of Twin Falls to the end of the asphalt section near Grandview Drive in Twin Falls.
Drivers should be prepared for minor delays and loose gravel throughout the 5.5-mile section. A 45-mph speed limit will be posted throughout the work zone. Observing posted speed limits and increasing following distance will reduce the risk of windshield damage caused by the loose gravel.
Seal coating and brooming the excess gravel is expected to be complete by Saturday (Aug. 11) with striping to follow.
A seal coat will also be applied to the frontage roads constructed as part of the $26.6 million project. Drivers should watch for flaggers and be prepared for delays in those sections of roadway.
Meanwhile, Crews will begin a project to apply an epoxy overlay to the Perrine Coulee Bridge on U.S. 93/Pole Line Road early next week, the Idaho Transportation Department announced. Traffic will be reduced to one lane in each direction between Canyon Crest Drive and Harrison Street for about three days.
Beginning Monday August 6 crews will clean the surface of the roadway and sidewalk prior to applying the epoxy resin and gravel aggregate. The maintenance project will cover the bridge and protect against cracking and corrosion, restore the surface strength and skid resistance, and improve lifespan of the bridge deck.
About half of the Perrine Coulee Bridge will be closed at a time while crews apply the overlay. Drivers are urged to use caution through the work zone and follow the reduced speed limit.
The Perrine Coulee Bridge is one of three structures included in this contract along with Raft River Interchange on I-86 and Juniper Interchange on I-84 where work is expected to begin later this month.
