The Idaho Transportation Department is hosting an open house on Thursday, March 6, to share information and gather community input about plans to improve U.S. Highway 91 between Siphon Road and Reservation Road to address increased growth.

The public is invited to view preliminary design plans in person from 4:30 to 6:30 p.m. at Tyhee Elementary School at 12743 W. Tyhee Road in Chubbuck. Community members are encouraged to stop by to learn about the project and provide feedback. Project staff will be available to answer questions.

Preliminary design plans currently include:

Widening US-91 between Siphon Road and Tyhee Road to two lanes in each direction with a center turn lane between Siphon Road and Tyhee Road.
Resurfacing US-91 between Tyhee Road and Reservation Road.
Improving residential access in the project area.

Those who are unable to attend in person are invited to view identical project information online and comment from March 6 to March 20 at itdprojects.idaho.gov/pages/us91-siphontoreservation.

“ITD recognizes how vital US-91 is to the Chubbuck area, and we want to be prepared as growth in the area continues,” Project Manager Bo Frasure said. “Input from the community will be essential as we move forward on this project.”

More information about the US-91 Siphon Road to Reservation Road project is available at itdprojects.idaho.gov/pages/us91-siphontoreservation.

Seal coating to begin in Preston next week

PRESTON – On August 25th the Idaho Transportation Department will begin a $433,000 chip seal coating operation on State Street in Preston. At the request of the city, ITD will also restripe the road to return it to a four-lane configuration. Work will continue until September 9th with a brief pause during the Labor Day weekend.

From the beginning of the project until the 29th there will be no parking on State Street. In addition, there may be up to 15 minute delays for motorists.

Chip sealing, also called seal coating, maximizes the taxpayers’ investment by extending the lifespan of the pavement. A sticky slurry is sprayed on the pavement, rock chips are applied on top of the slurry for a long-lasting seal. Hot, daytime temperatures are needed to ensure a successful application. Chip sealing protects pavement from sun, oxidation, weather, water, oil and gas, and improves friction for drivers.
