Traffic Alerts - I-17: Central Avenue Bridge Construction Project

Restrictions and Closures

ADOT urges you to slow down and use caution around construction personnel and equipment while the following restrictions are in place:

North- and southbound Central Avenue near the I-17 bridge will be narrowed to one lane, as work continues on the bridge replacement. These restrictions will be in place until fall 2020.

North- and southbound I-17 traffic will be running on the northbound half of the I-17 bridge at Central Ave, with two travel lanes in each direction. This shift is anticipated to remain in place until early 2021 when traffic will then be switched to the southbound side of I-17 for reconstruction of the northbound side of the bridge.

Schedules are always subject to change because of weather or other unforeseen factors.
