Traffic will be affected as the Idaho Transportation Department and contractor partners conduct inlaid striping operations on State Highway 33, U.S. Highway 20, and Interstate 15 Business Loop over the next two weeks.
Beginning today, lane closures will be in effect where work is currently underway on SH-33 between Sage Junction and Rexburg. Four miles at one time will be reduced to one lane, with flaggers and pilot cars directing traffic through the work area. Motorists should watch for reduced speed, large equipment and signs indicating construction ahead.
Roadways will be worked on in this order, with all operations expected to be completed by August 15:
- SH-33 between Sage Junction and Rexburg, milepost 59 to 78.
- US-20 west of Idaho Falls, milepost 301 to 307, beginning next week.
- I-15 Business Loop in Idaho Falls (Sunnyside Road from I-15 to Yellowstone Road).
- I-15 Business Loop in Idaho Falls (Yellowstone Road from Sunnyside to Broadway).
Operations on SH-33 and US-20 are being conducted during daytime hours. Crews will work through the night on the I-15 Business Loop in Idaho Falls.
A pilot car and flaggers will only be present on SH-33 this week. Traffic will be directed into one lane and continue to move around the work area on US-20 and I-15 Business Loop.
Inlaid striping is relatively unique in Idaho. The operation involves grinding into the pavement very slightly, creating recessed notches that paint is then applied within. This method aims to extend the life and reflectivity of pavement markings.

REXBURG—The Idaho Transportation Department, in partnership with Union Pacific Railroad, will close highways near several railroad crossings in May.
State Highway 33 from Rexburg to Sage Junction will close Monday through part of Tuesday as needed (May 19-May 20) as Union Pacific Railroad replaces crossings along this route. Motorists can take State Highway 48 to Roberts and Interstate 15 to Sage Junction as an alternative.
SH-48 through the town of Roberts will close through the weekend of May 31-June 3 as three parallel railroad crossings and paving are conducted there as well. I-15 can be accessed at the Osgood Interchange south of Roberts as an alternative.
Digital message boards will be in place along both routes prior to these closures to give motorists advance warning time for making alternative travel plans. Updates regarding these closures will be posted on the Idaho 511 app and at 511.idaho.gov.
Two projects are set to begin Monday to create a center mumble strip and add a passing lane on State Highway 33. Motorists will experience lane closures and delays at various times through the summer.
A mumble strip along the center line of SH-33 will be added to increase safety and avoid collisions from the intersection of State Highway 32 to the Wyoming state line. The mumble strip will not be added within the city limits of Tetonia, Driggs and Victor. All striping will also be redone. This project will close one lane in the current work area and be complete within two weeks. Mumble strips are similar to rumble strips but are rounded so noise is heard by the driver and less by surrounding homes and businesses.
Work on the addition of a passing lane, center and right turn lanes and the realignment of Baseline Road along SH-33 between Victor and Teton Pass also begins Monday. Drivers should plan for delays between 15 and 30 minutes as temporary signals will alternate traffic through the work zone from mileposts 151 to 153. Crews will remove outdated concrete cattle underpasses and widen the road to ultimately give motorists a chance to pass slow-moving vehicles before entering Teton Pass. This work will be complete mid to late-September.
Motorists should remember to use caution and be patient through construction zones as the Idaho Transportation Department and contractors work to make the road better for the future.

Starting in late May the Idaho Transportation Department will widen State Highway 33 near Victor to include a passing lane, center turn lane, and right turn lanes. Construction is anticipated to start on May 20.
Motorists can plan on one lane remaining open throughout construction, which is expected to last until early to mid-September. Fifteen-minute wait times between milepost 151 and 153 may occur as flaggers direct traffic. Cones will be moved out of the way of traffic each night, and all lanes will be open.
A new passing lane for eastbound traffic between milepost 151 and 152 will improve the flow of traffic on SH-33 before motorists begin to traverse Teton Pass. A center turn lane will continue after the passing lane to make it easier for drivers to access area subdivisions and Trail Creek Community Pond. Baseline Road will also be realigned to improve visibility at the intersection of SH-33.
Old cattle underpasses that are no longer used exist in three different areas along SH-33 where this work will be done. This means crews need to remove old cement structures, excavate the ground down eight feet and then rebuild one foot at a time to ensure road integrity. Motorists will note additional time spent on those sections of work, with crews present in those areas for longer and flaggers remaining overnight.
This project is made possible through a grant obtained by Teton County of Wyoming in partnership with ITD, Teton County of Idaho, the town of Jackson, the city of Driggs and others. Information about additional planned improvements through the grant can be found at tetonbuildgrant.com.

The Idaho Transportation Department is conducting exploratory drilling on State Highway 33 near the Wyoming state line Tuesday, April 30 and Wednesday, May 1. This section of the road is beginning to slide and the guardrail tip to the side. Geologists and materials crews are taking samples to get information on the cause and to install instrumentation for slide monitoring. No lane closures are in effect as a result of the drilling operation.
The samples collected from drilling will help ITD specialists know what is causing the road to slide, how far down it goes, and how fast it’s occurring. There are natural springs in this vicinity and around SH-33.
Instruments will also be placed in the ground to remain there so ITD can monitor movement. With data collected from drilling, work to ensure the needs of this section of road will be planned and executed in coming months.
Motorists are cautioned to be particularly aware of working crews, slow down, and move over when passing equipment.
