ITD completes I-84 shoulder widening, prepares for major construction in 2019
NAMPA – The Idaho Transportation Department will complete a project early next week to widen the shoulders on Interstate 84, clearing the way for major construction in 2019.
Motorists can expect brief delays on Sunday, Nov. 18 while crews stripe the reconstructed shoulders. Striping activities will be scheduled during daytime hours due to low overnight temperatures.
The newly reconstructed shoulders will serve as temporary travel lanes during major I-84 construction in 2019, including:
- Add a travel lane in each direction from Franklin Boulevard to Karcher Road.
- Construct auxiliary lanes between each interchange from Franklin Boulevard to Karcher Road. An auxiliary lane runs from one on-ramp to the next off-ramp. An example would be eastbound between Franklin Blvd. and Garrity Blvd.
- Reconstruct the Northside Blvd. Interchange into a high-capacity Single Point Urban Interchange (SPUI), similar the interchanges at Ten Mile, Meridian, or Broadway.
- Rebuild the Karcher Overpass — the bridge east of the Karcher Road Interchange.
Construction on I-84 in Nampa will continue through 2020.
“The next few years will involve multiple projects and multiple stages of design and construction,” said Amy Schroeder, ITD Program Manager. “ITD will continue to equip motorists and residents with the information they need to participate in the design process and plan ahead during construction.”
West of the Karcher Interchange, ITD is moving forward with a detailed environmental study and traffic analysis of I-84 in Caldwell. The department will hold public meetings in early 2019 to gather input on potential improvements.
ITD has allocated $330 million in funding for I-84 in Canyon County.
