The RCOC was seeking a solution to eliminate congestion and improve safety and traffic flow at this constrained intersection located along two minor arterial roadways.

As a sub to OHM, MTJ provided operational analysis (Rodel), development of 3 concept alternatives, and preliminary/final horizontal design for this intersection. MTJ conducted a traffic planning level review of the system of the existing context and intersections.

MTJ developed a “right-sized” roundabout that accounts for designing vehicles and avoiding unnecessary realignments that do not add safety or operational value. Geometric elements were designed to achieve accessibility objectives while maintaining essential design elements that promote safety for all modes – vehicular and pedestrian. Key features include:

-Flared two-lane entries

-Yield-right-turn lanes

-Long splitter islands for channelization due to higher transitional approach roadway speeds & context
