ADOT schedules overnight work on I-17 next week
Lane closures will be necessary when the Arizona Department of Transportation (ADOT) shifts traffic on the northbound Interstate 17 at Cordes Junction onto the new bridge over Big Bug Creek.
A news release from ADOT reports that the traffic shift will require northbound and southbound lane restrictions and two nights of periodic full closures of as long as 30 minutes at a time between 11 p.m. and 3 a.m., Monday and Wednesday.
The closures and restrictions will include:
Sunday, 10 p.m. to 6 a.m. - the southbound I-17 ramp to Highway 69 will be closed to allow crews to work on the new bridge over I-17. Traffic will be detoured three miles southbound on I-17 to Bloody Basin Road (Exit 259) and then directed to turn around and use northbound I-17 to reach the Highway 69 exit.
Monday, 7 p.m. to 6 a.m. - southbound I-17 will have alternating lane restrictions and intermittent 30-minute southbound closures from 11 p.m. to 3 a.m. to allow crews to switch traffic onto the new bridge.
Tuesday, 7 p.m. to 6 a.m. - both directions of I-17 will have alternating lane restrictions to allow crews to set temporary barrier along the new alignment onto the Big Bug Creek bridge.
Wednesday, 7 p.m. to 6 a.m. - both directions of I-17 will have alternating lane restrictions and another night of intermittent 30-minute northbound closures from 11 p.m. to 3 a.m. to shift traffic onto the Big Bug Creek bridge.
Thursday, 7 p.m. to 6 a.m. - both directions of I-17 will have a left-lane restriction to allow crews to strip pavement from the pre-existing detour route.
ADOT is encouraging drivers to adjust their travel schedules in order to avoid the closures during these hours or allow extra travel time to reach their destination.
The work is part of a $50 million project to reconstruct the I-17/Highway 69 traffic interchange.
