The detour off South Frontage Road will be gone on Wednesday morning. When it’s reopened, South Frontage will have three travel lanes. A new far-left fourth lane will be closed to accommodate construction of 101 College St., according to a release. Over the summer and into the fall, drivers using the detour off South Frontage Road to get onto the interstate highways were making an improper turn, potentially causing a safety problem, according to Mariotti. “We’re excited to see the progress happening as we continue to the work to reconnect the Hill to downtown,” Mayor Justin Elicker said in an emailed statement. “The reopening of South Frontage Road is great news as it will help reduce congestion in the area and improve safety for all travelers.”
