As a result, the State has a responsibility to manage and maintain effectively each highway within the State highway system to preserve its functional integrity and public purpose for the present and future generations. Land development activities with unrestricted access to State highways impair the safety and operation of the State highway system and damage the public investment in that system. Owners of property which abuts a public road have a right of reasonable access to the general system of streets and highways, but not to a particular means of access. The right of access is subject to regulation for the purpose of protecting the public safety, health, and welfare.Highway access management is beneficial for the State highway system. The purpose of this policy is to establish the implementation of access management as a priority of INDOT. To this end, INDOT will develop and maintain an access management program for the State highway system to promote the safe and efficient movement of people and goods within the State, preserve the functional integrity of and the public investment in the system, and encourage economic vitality in the State.For more information…Indiana Access Management Study Web Site:http://www.in.gov/indot/3273.htmTRB Access Management website:http://www.accessmanagement.info/
