Implementing MoDOT’s Access Management Guidelines Along Route 763

The Missouri Department of Transportation (MoDOT) selected HDR to provide design services to upgrade Route 763 in Columbia, Missouri to a five-lane principal arterial. A key element included within the design process of upgrading the existing two-lane roadway to a five-lane roadway was the implementation of access management throughout the three-mile corridor. The existing corridor already was beginning to see the importance of access management based on its crash history causing MoDOT to proactively close driveways and place temporary channelizers within the corridor. The focus of this paper is to highlight the importance of developing and implementing access management alternatives throughout the design process. Through close collaboration with stakeholders (City of Columbia, Boone County, North Area Columbia League), several access management design features were incorporated prior to as well as during the design process. The following includes a list of the major elements: (1) Controlled access throughout corridor; (2) Channelized/divisional medians; (3) Unsignalized left turn pockets; (4) Right-In/Right-Out (RIRO) access only; (5) Design of signalized intersections to accommodate U-turns; (6) Adherence to principles throughout design process as well as during the right-of-way negotiations; and (7) Consolidation of roadways to form a five-leg roundabout. Another element that became evident during the stakeholder meetings was creating a pedestrian friendly environment to complement both the residential and commercial development located within the corridor. The following includes some of the major elements that were incorporated into the project: (1) Sidewalks along both sides of the roadway (typically not done); (2) Australian Right Turn Design Concept (decreases crosswalk length); (3) Count-Time Downers at Crosswalks; (4) Blank-Out Signs used for No Right Turn on Red indications; and (5) All overhead utilities were buried along the corridor
