ITD urges drivers to share the roadway

With a winter storm forecasted for the weekend, the Idaho Transportation Department (ITD) wants to remind drivers to share the road with snowplows.

Snowplows push snow off the road and deploy a variety of salt products to keep roadways bare and wet most of the time during storms. Drivers also need to do their part to keep everyone safe on the road.

“Slow down in snowy conditions, and give yourself extra time to get where you need to go this weekend,” Foreman Chuck Sharp said.

Aside from leaving early and using caution when driving in the snow, here are five tips to help share the road with snowplows:

  • Don’t crowd the plow. Stay back around 50 feet.
  • A snowplow has a 12-foot front plow and 10-foot wing plow and takes up the entire lane. Don’t crowd the centerline.
  • The safest spot is behind the plow. Only pass when safe to do so.
  • Never pass on the right.
  • Before traveling, check for road conditions that are updated 24/7.

While operators work in the worst weather, often the biggest threat to their safety is other drivers. Last winter, 17 plows were hit in Idaho.

“Plows weigh around 58,000 pounds fully loaded,” Sharp said. “Drivers who run into this heavy equipment trying to pass are risking their own safety, and the safety of others on the road when the plow isn’t able to continue working due to damage.”

Lane closures next week on the Perrine Bridge

Drivers should plan for alternating lane closures next week as crews continue making repairs to the Perrine Bridge.

Next week workers will apply a sealant to both sidewalks on the bridge to protect them from weathering. The closures will be staggered so only one lane or one sidewalk will be closed at a time. Lanes will be closed so that the contractor can access the sidewalks and will be open at night when workers are not present.

  • Wednesday through Friday (Nov. 15-17)
    • The sidewalk on the west side of the bridge will close for repairs. The adjacent southbound lane will be closed.
  • Friday through Sunday (Nov. 17-19)
    • The sidewalk on the east side of the bridge will close for repairs. The adjacent northbound lane will be closed.

Maintenance will last through spring of 2024 and includes repairs to the sidewalks, the railing and cracks to extend the lifespan of the bridge. Some of the steel supports will also be painted for protection from weathering.

Activities are dependent on weather conditions. Travelers should stay up to date on impacts by visiting or downloading the 511 app.

Open house next Wednesday to share plans to replace the US-30 Dry Creek Bridge

The Idaho Transportation Department (ITD) invites the public to attend an open house next Wednesday to share input on the replacement of the Dry Creek Bridge located on U.S. Highway 30.

Originally built in the 1930s, the existing bridge is a two-lane structure that crosses Dry Creek just north of Murtaugh Lake. Proposed plans include updating the guardrail and widening the shoulders, as well as building the new bridge in the same spot or shifting the structure slightly to the north or the south. The department is also seeking comment on ways to preserve historical aspects of the bridge.

The open house will run from 3:30 p.m. to 6:30 p.m. on October 11 in the Murtaugh High School Cafeteria at 500 Boyd Street. An online option will be available at from October 11 to October 18 to give members of the public who cannot attend in person a chance to participate.

“The bridge has served the community for nearly 100 years and is nearing the end of its lifespan,” ITD Project Manager Brent Brumfield said. “It is important that we preserve the history of the bridge while ensuring the public can cross Dry Creek safely.”

The bridge is scheduled for replacement in 2026. For more information, or to participate in the online open house, visit

Daytime lane closure to start Saturday on the Perrine Bridge

Inspection underneath the bridge

Daytime lane closures are expected to start early Saturday morning on the Perrine Bridge while staff inspect the structure.

The routine inspection may take up to six days to complete, with crews on site each day between 5 a.m. and 3 p.m. Only one lane will be closed in one direction at a time. Work will not affect the sidewalks.

“We are starting this work early and on the weekend when there’s less traffic,” Bridge Asset Management Engineer Alan Buehrig said. “We will be using a special truck to inspect areas underneath the bridge and will move back and forth between both sides, so motorists should be prepared for one less lane in either direction, depending where we’re working.”

Drivers should plan for delays by checking as there is already active construction on the bridge. While the inspection will take less than a week, ongoing maintenance is planned through spring 2024.

Perrine Bridge maintenance now underway with minor traffic impacts

Routine repairs on the Perrine Bridge near Twin Falls are now underway as the contractor starts setting up staging areas for equipment and scaffolding to access areas underneath the bridge. Work is not expected to impact traffic at this time.

Maintenance efforts will extend the lifespan of the bridge and include repairing the sidewalks, the railing and cracks. Some of the steel supports will also be painted for protection from weathering.

Lane closures are not expected for a few weeks, but mobilization this week is the beginning of a maintenance project that will last through spring of 2024. Signs on the highway will advertise upcoming closures to give drivers’ time to adjust their commute, and sidewalks on either side of the bridge will remain open for the duration of construction.

ITD schedules routine bridge maintenance projects to ensure the bridge’s longevity for years to come.

“Maintenance now could prevent future closures,” District Engineer Jesse Barrus said. “It’s far more effective to schedule these routine maintenance repairs and plan for it now than address issues later. Our goal is to ensure crews work quickly but safely.”

A new traffic signal will be installed on State Highway 75 at Ohio Gulch Road north of Hailey starting Tuesday. The signal is expected to be fully operational by January.

Crews will first prepare the site for signal pole installation with the majority of work underground. Then they will build the signal by placing the poles and mast arms.

During construction traffic will be reduced to a single lane intermittently as each corner of the intersection is worked on. Motorists will need to plan for delays during the day and are advised to slow down and watch for workers and heavy equipment along the highway.

“We are pleased to begin construction for this much-anticipated traffic signal for the city of Hailey,” District Engineer Jesse Barrus said. “It’s been a long journey to get here, and we appreciate everyone’s patience as we start construction and take the needed time to ensure crews work safely while they complete the project.”

Variable speed limit signs in place in the I-84 South Jerome to Twin Falls work zone to improve safety

JEROME – The Idaho Transportation Department (ITD) has installed variable speed limit signs to improve safety as crews widen I-84 between the South Jerome and Twin Falls Interchanges. The new signs are controlled remotely, allowing ITD to lower speeds when crews are working near traffic.

The current posted speed limit in the work zone is 70 mph. When crews are working near traffic, ITD will lower the speed limit, and a flashing beacon will notify drivers that speed limits have been lowered. When crews are not as close to traffic, ITD will raise the speed limits to 70 mph.

Variable speeds have been successfully implemented in other work zones, including the one on I-84 between Caldwell and Nampa. Research shows that variable speed limits reduce crashes, reduce travel times, and improve safety.

The signs will be removed when construction is complete in late fall of 2025.
