Since 2007, the County had been studying the corridor in order to determine what types of changes would best improve the 3.5 miles between Ackman Road and County Line Road. The Phase I Preliminary Engineering Study concluded in 2013. The next stage (Phase II) was to determine the details required to move forward and allow final construction drawings to be prepared. It was planned to widen Randall Road to three lanes in each direction. The plan was to design the corridor to balance safety, access, and level of service. Intersections and businesses close to the actual roadway made some areas of this project challenging – especially at the Algonquin Road intersection.
During Phase II, the Design Team reevaluated the previously studied alternatives for this area. They took into account updated traffic projections, access, safety and socioeconomic data. Then, the Team refined the design to balance the needs of the motoring public (i.e. safe and efficient movement of traffic) with access to businesses along the corridor. At the September 3, 2014 Transportation Committee Meeting, two alternative designs were considered that took into account the reevaluation of traffic projections and input obtained from project stakeholders.

The first design alternative was a modification to the Continuous Flow Intersection (CFI) that was presented in Phase I, now referred to as a Displaced Left Turn (DLT) Intersection.

In September 2014, the Transportation Committee passed a resolution supporting a conventional intersection design for the Randall/Algonquin intersection with modifications as suggested by various stakeholders during the outreach process. These modifications were referred to in the resolution approved by the Transportation Committee as Exhibit A.
