Black Canyon City, Arizona – Drivers on Interstate 17 in central Arizona should prepare for multiple overnight lane restrictions and ramp closures this week as construction continues on the I-17 Improvement Project.
According to the Arizona Department of Transportation, work will affect both northbound and southbound traffic between Anthem and the Sunset Point Rest Area beginning Monday night and continuing through Saturday morning. The scheduled closures will allow for paving, bridge work, concrete installation, and lane striping.
Southbound I-17 will be reduced to one lane with alternating right- and left-lane closures between mileposts 253 and 242 each night from 7 p.m. to 7 a.m. beginning Monday, June 16, through Saturday, June 21. An additional single-lane restriction is planned between mileposts 239 and 236 on Tuesday night for drainage and bridge work.
Ramp closures include the southbound off- and on-ramps at Bumble Bee Road (exit 248) from 7 p.m. Thursday to 7 a.m. Friday, and the southbound off-ramp at Coldwater Road (exit 244) on both Monday and Wednesday nights for utility installation.
Northbound I-17 will be narrowed to one lane nightly from 6 p.m. to 6 a.m. between Anthem Way and Black Canyon City (mileposts 229 to 243) starting Monday, June 16, through Thursday, June 19, for permanent striping. Additional one-lane closures are scheduled near mileposts 244 and 245 Thursday night for a traffic shift, and mileposts 241 to 244 Tuesday night for bridge work.
Flex lanes will be used to divert northbound traffic between Coldwater Road and Sunset Point. The northbound on-ramp at Coldwater Road will also close Thursday night for related adjustments.
ADOT advises drivers to plan for delays and use caution in all construction zones. Schedules may change due to weather or other unforeseen conditions.
