BEST PRACTICE:

G4−7: Closure of Entrance Ramps During Construction

DESCRIPTION:

The best practice is the closure of entrance ramps during construction. One or more ramps are closed within a work zone, and possibly preceding a work zone if it is deemed necessary. Entering traffic from ramps adds demand to the facility and creates turbulence due to merging movements. This can increase congestion, particularly in work zones with reduced capacity. By limiting the frequency of entrance ramps for certain work zones, the Ohio Department of Transportation (ODOT) and its contractors can improve mobility and safety through a corridor.

REASON(S) FOR ADOPTING:

The primary reason for closing entrance ramps is to reduce accidents in the construction work zone. Closing ramps can address the issues of a reduced weaving area and increased congestion.

PRIMARY BENEFIT(S):

A reduction in the number of crashes and less congestion in the work zone.

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

All high−volume freeway projects.

STATE(S) WHERE USED:

Ohio
