Rt. 31 bypass bridge work to close lanes on Algonquin Road

Beams to be placed this week at Algonquin Road; will cause closures

ALGONQUIN – Beams for the new Route 31 bridge over Algonquin Road are scheduled to be set this week, which would lead to periodic lane closures in both directions, the Illinois Department of Transportation said.

Setting the bridge beams will require intermittent 10-minute lane closures of both directions of Algonquin Road between 9 a.m. and 3 p.m.

The work is dependent on the weather, IDOT said.

The construction is part of the new Route 31 Western Algonquin Bypass, which is being built to alleviate traffic congestion at Route 31 and Route 62. The new road would divert through-traffic away from downtown Algonquin.

Construction of the bypass is costing $33.3 million. Work started more than a year ago, and it is expected to be completed in fall of next year. 

Currently, only one lane in each direction on Algonquin Road is open in the project area.

IDOT expects by mid-November that two lanes in each direction on Algonquin Road will be open after the bridge beams are set, the entrance and exit ramp pavements are placed, and lighting and signal installations foundations are prepared.

There are certain parts of the project that are almost done or already completed.

The new intersection of Route 31 and Main Street/Quarry Access Road is about 90 percent done, IDOT said. The new Quarry Access Road has been completed, but final surfacing remains.

Retaining wall work near Edgewood Drive is near completion, and the new right-turn lane for southbound Route 31 to westbound Edgewood Drive is being constructed.

As part of the project, the village had to close Towne Park to allow for construction of the bypass.

Workers have completed the Crystal Creek realignment. There is still work to be done on the construction of the three bridges over Crystal Creek as well as various retaining walls.
