I- 17 will close overnights at the I-17/I-40 interchange in Flagstaff for the next two weeks while crews set up support structures in order to replace the I-40 bridge decks. Beginning Sunday, northbound I-17 will close where the highway passes under I-40 nightly from 8 p.m. to 5 a.m. through next Friday. Then Sunday, southbound I-17 will close under I-40 nightly from 8 p.m. to 5 a.m. through Friday, June 15th. The $10 million project includes replacing the I-40 bridge decks in each direction over Beulah Boulevard, immediately west of I-17, as well as the westbound bridge deck over I-17. The eastbound I-40 bridge over I-17 will get a new concrete surface.The project will also increase the cross slope of the roadway over the renovated bridges, helping to drain water off of the road surface and includes guardrail and paving work.
