Lane Closure Policies
Many agencies have policy provisions that address specific aspects of decision-making during project delivery. Agencies may choose to develop and implement policy provisions in the form of mandated requirements and/or in the form of policy guidance, as appropriate to their individual operating environments. Several States have policy provisions for lane closures. These lane closure policies, or strategies, provide guidance in determining permitted lane closure times, which define what times of the day, week, or season a lane closure is allowed on a facility and at a specific location or segment.
Fact Sheet - Lane Closure Policies and Management Systems
This FHWA fact sheet defines lane closure policies and management systems. It provides examples of several states that have developed lane closure policies and systems to aid in the scheduling of work zones and to improve mobility by restricting lane closure hours during peak travel times and coordinating lane closures to manage combined impacts.
Lane Closure Policy Development, Enforcement, and Exceptions: A Survey of Seven State Transportation Agencies
This report (PDF 872KB) developed by the Center for Transportation Research and Education at Iowa State University examines the lane closure policies of several State DOTs.
Colorado DOT
Each Colorado DOT (CDOT) region has its own lane closure policy. While the CDOT methodology used to determine lane closure impacts is applied uniformly across all regions, the criteria and policies for closing lanes are region-specific. For example, daytime lane closures are prohibited in the Denver Metro area, but are allowed in more rural areas.
Maryland State Highway Administration
The Maryland State Highway Administration (MDSHA) Lane Closure Analysis Guidelines (PDF 54KB) focus on mobility impacts. However, MDSHA recommends that safety impacts also be considered during the evaluation of lane closures. MDSHA can waive mandatory conditions contained in the guidelines upon approval by the Chief Engineer. Pages 6 and 7 include flow charts outlining the lane closure guidelines procedure for arterials and freeways.
