Construction on I-17 at Munds Park resumes March 22
Next week, the Arizona Department of Transportation (ADOT) will begin the second phase of a reconstruction of the Interstate 17 Munds Park traffic interchange, about 20 miles south of Flagstaff.
The second phase of the $10 million project includes rebuilding the southbound I-17 bridge and ramps, as well as the realignment of Pinewood Boulevard, according to a news release from ADOT.
Southbound traffic will be shifted to a single lane on the northbound bridge while the southbound bridge is under construction.
Starting on Thursday, March 22, northbound I-17 lane restrictions will be required while crews re-stripe the roadway and a traffic detour to shift southbound traffic.
After the detour is striped, the southbound bridge will be closed, and motorists traveling southbound on I-17 will be detoured to cross over the median and use the northbound lane. All on and off ramps will remain open.
The first phase of the project, which included the reconstruction of the northbound I-17 bridge and ramps, was completed last year; the southbound bridge is scheduled to be complete this fall.
The entire project involves the replacement of two 25-foot-long bridges that date back to 1958 with two new bridges measuring 100 feet long.
The speed limit will be reduced throughout the construction zone, and ADOT is reminding drivers to proceed through the work zone with caution, and be alert for construction equipment and personnel.
