- ACHD's map of a detour around Hill Road between 28th and 36th streets in Boise.
The Ada County Highway District is alerting the public to road closures on and near Hill Road, as well as the beginning of chip sealing season.
Beginning Wednesday, May 18, ACHD will close Hill Road between 28th and 36th streets for construction on the 36th Street/Hill Road/Catalpa Drive Roundabout Project, as crews put the finishing touches on the road and roundabout located near Hillside Junior High School.
The closure—expected to last about a week—is meant to allow ACHD to complete the roundabout project ahead of schedule. Hill Road traffic is being detoured along 36th and Taft streets, though the road will remain open for emergency access.
"We understand that this closure will present an inconvenience to the travelling public; however, we believe that this is the most convenient option for motorists," ACHD stated in its announcement. "The other alternative involved lane restrictions with heavy flagging, which would have resulted in major delays for motorists."
In addition to the Hill Road closure, ACHD is bracing for chip seal season, which will begin Tuesday, June 7 and won't come to an end until late August. Projects include repairing road surfaces, tree trimming, curb replacements and "dig-outs"—replacing road subgrade that has failed.
People living in areas affected by chip seal operations will receive notices five-10 days before work begins. Weekly progress reports are available via the ACHD automatic messaging system at 208-345-7880. Residents living west of Whitewater Boulevard and 28th Street may call 208-387-6350 and residents living east of Whitewater may call 208-387-6325—or visit the ACHD website.
