The use of temporary median crossovers in work zones allows for the closure of one side of a multi-lane roadway while maintaining two-way traffic on the opposite side. This process provides the ability for construction and maintenance crews to construct, rebuild, or perform maintenance on a portion of one direction of a roadway segment while allowing roadway users continued access through the facility. A number of behavior studies were conducted on singlelane and dual-lane crossovers at work zone locations in the State of Nebraska resulting in general guidelines for optimal geometric design features of such work zone elements.
