The term “two-lane rural highway” as used in this chapter, refers to roadways in un-developed areas that have one-lane of traffic in each direction. Access to these facilities is controlled through driveway locations and intersecting roadways. Two-lane rural highways usually do not have any type of median barrier. See more This subsection includes information on the following basic design features for two-lane rural highways: 1. Geometric Design Criteria for Two-Lane Rural Highways; 2. Access Control; 3. Transitions to Four … See more The installation of access driveways along two-lane rural highways must be in accordance with the Access Management Manual. Frontage … See more Passing sight distance is the distance required by a driver to make a passing maneuver without cutting off the passed vehicle and before meeting an opposing vehicle.
