Randall Road at U.S. Route 20 / Weld Road (East) in Elgin, Illinois is undergoing Phase I engineering for proposed intersection improvements. The intersection improvements are intended to improve traffic flow, increase capacity, and enhance safety for the motoring public. As proposed, the improvement would close the Weld Road east access at Randall Road in order to construct a new entrance ramp from northbound Randall Road to eastbound U.S. Route 20. The new design will create a T-Type intersection and eliminate over a dozen conflict points thereby significantly reducing the potential for crashes. Vehicle delay is reduced and capacity is increased as a result of the elimination of several vehicle movements.
￼The intersection of Randall Road at U.S. Route 20 / Weld Road (East) currently experiences vehicle queues extending past existing turn lane storage lengths. Since Randall Road is a coordinated Strategic Arterial Route (SRA) with a long cycle length to accommodate the large volume of through movements, high delays on the side roads occur. The left turn and side street approaches do not have sufficient signal time allocated, resulting in aggressive driving. The southbound Randall Road right turn to U.S. Route 20 cannot access the right turn lane due to long through traffic queues. The existing cross-section of this intersection is no longer effectively serving the 50,000 + motorists using it each day.
Three alternatives are being reviewed as part of the Study:
The Free Flow Entrance Alternative is the only alternative considered that significantly reduces congestion and improves safety. It is favored as the Preferred Alternative and is supported by Illinois Department of Transportation and U.S. Federal Highway Administration. The Free Flow Entrance Alternative includes:
The Alternative minimizes the following environmental impacts:
