Driveways, Entrances, and Sight Distances

If someone wants to put in a new house or business on one of your town roads or streets:

  • Does your town have any control over this process?
  • Do some roads seem to have too many entrances or driveways onto them now?
  • Is there a safety problem because the entrance is near a hill or curve without enough sight distance to see approaching vehicles?

If your town would like to take control of entrances onto your local roads, you will be getting into the field of “access management”. In traffic terms, you will be providing safe access to/from land, while conserving the ability of a road to move traffic safely and efficiently. 

Why is it so important?

It increases safety by assuring predictable, well-designed, and highly visible locations for vehicles entering/exiting the road. On a higher speed road, fewer access points means fewer conflicts and safer travel.

It controls public costs by improving and conserving the road’s ability to handle traffic and drainage. Poorly designed and located driveways can create road-damaging runoff and erosion and icing conditions. 

On rural state and state aid highways (non compact), the MaineDOT issues permits pursuant to Title 23, Sec 704. Any property owner wanting to construct a driveway or entrance onto the state’s collector and arterial highways must apply for a permit.  This even applies when there is a “change of use” of an existing or old entrance.  For a copy of the rules or to request an application form, contact the MaineDOT Region Office nearest you or check the web at:  http://www.maine.gov/mdot/ppp/accessmgmt/index.htm.

For local roads, most of Maine's "state urban compact" communities, have their own "entrance" policies or ordinances which may be a good resource to develop for your town. If they do not have their own, then the MaineDOT rules apply by default.  In the near future, the Center will be publishing its own publication and "model ordinance" for use by Maine towns.
