Work to begin on 5-way intersection in Crystal Lake

Drivers may see delays at intersection of Routes 31 and 176

CRYSTAL LAKE – Crews are expected to start relocating utilities near the intersection of Route 31, Route 176 and Terra Cotta Avenue this week ahead of a $10.2 million road construction project.

The Illinois Department of Transportation will reconstruct the five-way intersection to accommodate two lanes in each direction. It will add dual left-turn lanes and dedicated lanes for right turns. The traffic signal also will be replaced.

Terra Cotta Avenue, the fifth leg of the intersection, will end in a cul-de-sac. Once Terra Cotta Avenue is permanently closed, drivers will have to use eastbound Route 176 and southbound Smith Road to get there.

Drivers likely will see minor delays and sporadic lane closures on weekdays as the utility work gets under way. Once roadwork begins later this fall, the delays could become more significant as traffic slows and the lanes are narrowed. One lane will remain open in each direction during construction, IDOT spokesman Guy Tridgell said.

He encouraged drivers to anticipate delays, allow extra travel time and stay alert when traveling through the area.

Addison-based R.W. Dunteman Co., the prime contractor, is tentatively scheduled to complete the project by November 2013.

The intersection improvement project has been in the works for several years. It comes amid a busy construction season in McHenry County.

Details on the project, including traffic impacts, are available online at
