I-84 expansion will require extended ramp closures at Franklin Road Interchange in Caldwell this summer

The Idaho Transportation Department (ITD) is nearing a major milestone in the Interstate 84 widening project in Caldwell, bringing extended ramp closures and traffic changes near the Franklin Road Interchange (Exit 29).

Between June and September, each of the ramps at the Franklin Road Interchange will close for six weeks. The closures will allow crews to rebuild the ramps and connect them to new lanes on I-84.

Although exact dates are subject to change due to weather and other factors, ITD expects:

  • On June 19, the westbound off-ramp will close at 10 p.m. and remain closed for six weeks. Drivers will be detoured to 10th Avenue, where they can turn around and access Franklin Road from eastbound I-84.
  • On June 26, the eastbound on-ramp will close at 10 p.m. and remain closed for six weeks. Traffic will detour down 21st Avenue to Blaine Street, then west to the 10th Avenue Interchange.
  • On June 26, Linden Street will close under I-84 at 10 p.m. until late 2022 while crews finish the reconstruction of the underpass.

Once these two ramps re-open in late July, the other two ramps will close until early September. In addition to the extended closures, motorists can expect occasional nighttime lane restrictions on I-84 and ramps in the area. To request email or text updates about upcoming closures, text 84CORRIDOR to 1-866-483-8422.

“We have been working with our engineers and community leaders since 2020 to determine the best way to deliver this complex project while keeping traffic moving,” said Shawna King, ITD Design/Construction Engineer. “We ask motorists to be patient this summer and drive safely. We will keep everyone informed and look for every opportunity to expedite the process.”

ITD is expanding I-84 to three lanes in each direction between the Franklin Road Interchange in Caldwell and the Karcher Interchange in Nampa. Traffic will be shifted to the newest lanes in the I-84 median in June, allowing crews to begin rebuilding the existing outside lanes.

Construction on I-84 in Caldwell will be complete in 2023. For more information, visit itdprojects.org/84corridor, email 84corridor@itd.idaho.gov or call (208) 334-8002.

Construction underway on State Highway 21 widening project in Boise

The Idaho Transportation Department (ITD) has started construction to widen State Highway 21 between Technology Way and Surprise Way in Boise.

The project began Monday, May 16 and is expected to finish in late July. Planned improvements include a new center turn lane, wider shoulders, and dedicated right turn lanes at the intersections of Grand Forest Drive, Lake Forest Drive, Old Oregon Trail Road, and Surprise Way. An acceleration lane will also be installed for traffic turning onto southbound SH-21 from Surprise Way. When complete, this stretch of highway will feature two 12-foot wide travel lanes, a 14-foot center turn lane, and 6-foot shoulders.

Construction will begin on the south side of the highway. When paving is done, traffic will shift to the new pavement as crews complete paving on the north side of the road.

The anticipated work schedule is Monday through Friday, 7 a.m. to 7 p.m., with work pausing on Memorial Day, Independence Day, and July 5.

Motorists should plan for reduced speeds through the construction zone, traffic shifts, and periodic delays with flaggers directing traffic. Access will be maintained to all neighborhoods throughout the project. ITD and the Idaho State Police urge motorists to slow down and pay attention when driving in work zones, where increased speeding fines and other penalties apply. Please plan ahead and visit 511.idaho.gov for information on the state highway or interstate system.

Work Zones are a Sign to Slow Down

Work zones are a sign to slow down

National Work Zone Awareness Week is April 11-15

IDAHO – National Work Zone Awareness Week (NWZAW) will be observed April 11-15 with this year’s theme of “Work Zones are a Sign to Slow Down.” The Idaho Transportation Department (ITD) is asking motorists to observe NWZAW and prepare to safely drive through work zones across Idaho.

As part of NWZAW, Idahoans are encouraged

to participate in Go Orange Day on April 13 by wearing orange as a visual reminder of work zones. Photos can be posted on social media using the hashtags #NWZAW and #GoOrange4Safety.

The awareness week ends with a moment of silence on April 15 for people killed in work zone incidents.

Statistics from the National Work Zone Safety

Information Clearinghouse demonstrate the importance of work zone safety and participating in NWZAW to spread the message that everyone has a role in getting roadway workers home safely.

  • There were 762 fatal crashes in work zones resulting in 842 deaths in 2019.
  • Of the 842 fatalities in 2019, 135 were roadway workers.
  • Most people killed in work zones were motorists, passengers, and pedestrians.

NWZAW has been observed for more than 20 years and was launched as a public awareness campaign to help everyone understand they play a role in keeping motorists and roadway workers safe.

As construction season kicks off around the state, it’s important for drivers to remember that work zones come in all shapes and sizes. They can be long or short duration and can occur anywhere, from the middle of a large city to even the most rural routes. ITD encourages all motorists to plan ahead, follow signs, and drive engaged each time they get behind the wheel.

To learn more about NWZAW, visit nwzaw.org.
