TUCSON (KVOA) - Transportation crews are working on a traffic switch on the north side of the Interstate 10 and Houghton Road interchange that will continue through the night.
According to reports, traffic signs will be moved further north of the interchange, and shift the westbound I-10 entrance ramp north of the existing ramp.
The construction began at 9 p.m. on Monday and will last until 5 a.m. on Tuesday.
Motorists are advised to plan for delays.
The project will pick back up next week for the second phase.
According to a tweet by ADOT, crews will pour the bridge deck for the new Houghton bridge.
Work for that project will be held between 9:30 p.m. May 10 and 5:30 a.m. May 11.
