Best Practice

BEST PRACTICE:

G1−7: Total Road Closure

DESCRIPTION:

The highway is closed to allow unrestricted contractor access to the roadway.

REASON(S) FOR ADOPTING:

This practice, when combined with incentive/disincentives, significantly reduces the time to complete work.

PRIMARY BENEFIT(S):

Significant reductions in project construction time, which results in less delay to motorists. Also, as a result of shorter construction time, less total traffic is exposed to work zone hazards and the challenges of changing work zone traffic control.

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

The Michigan Department of Transportation has applied total closures to urban or suburban freeways, in areas where local street system or other freeway segments exist to handle the diverted traffic.

STATE(S) WHERE USED:

Michigan
