Truckers who travel through northern Arizona will likely begin seeing travel delays and lane closures next month near the I-40/I-17 interchange near Flagstaff as part of a construction project.

The Arizona Department of Transportation says the project will replace the I-40 bridge decks in both directions over Beulah Boulevard, west of I-17, as well as the westbound bridge deck over I-17. Additionally, the eastbound I-40 bridge over I-17 will get a new concrete surface.

“This work is needed to keep the I-40 bridges in top shape for commercial traffic and passenger vehicles using this key northern Arizona corridor,” said Audra Merrick, district engineer for ADOT’s North Central District.

ADOT says there will be multiple overnight, one-directions closures of Beulah Boulevard under I-40. The I-17 northbound to I-40 westbound ramp will be closed from mid-April through December, and the I-17 southbound to I-40 eastbound ramp will close for a couple weeks in mid-June.

The agency says drivers going to or through Flagstaff will need to plan for extra travel time. Detour routes will be clearly marked by signs, ADOT adds.

Once the project begins, traffic alerts for the area can be found here.
