BEST PRACTICE:

A1−5: Ramp Closures During Reconstruction

DESCRIPTION:

The Oklahoma Department of Transportation (ODOT) considers implementing ramp closures on all projects during reconstruction efforts on Interstates and freeways. ODOT conducts a public hearing for the surrounding neighborhoods to notify the public of the upcoming closures and to address the concerns expressed by the public. Typically, this is done just prior to closing the ramps.

In the future, ODOT plans to conduct the public hearings during the planning and design phases to ensure that all local concerns are addressed and that no local economic hardship will result from the ramp closures. ODOT plans to distribute questionnaires after completion of the construction project to determine how the local population was affected and what improvements can be made to the ramp closure process.

REASON(S) FOR ADOPTING:

This policy was initiated to facilitate reconstruction and improve public relations when existing ramps must be closed for rehabilitation projects.

PRIMARY BENEFIT(S):

The primary benefits are facilitating and accelerating reconstruction. These in turn reduce motorist delay and improve safety. The secondary benefits derived from this practice are increased public awareness of construction projects and work zones, less confusion of local citizens seeking alternate routes, and occasionally, new ideas on different approaches to closing the ramps.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

This practice mainly affects the high−speed/high−volume, access−controlled interstates, and freeways during rehabilitation and reconstruction.
