100 KM/H VS 110 KM/H

ASK US WHY

A reader who frequently does the drive between Halifax and the Third is wondering why the posted speed maximums on the divided highways seem to vary. So, we got in touch with the Department of Public Works for the answer.

“The Department has a policy for permitting 110 km/h posted speed limits on divided highways,” says department spokesperson, Gary Andrea. “For Highway 125 and several other divided highways across the province with a narrow or jersey barrier medians, they do not qualify to be posted at 110 km/h.”

Jersey barriers, also known as jersey walls and jersey bumps, are those concrete barricades that separate lanes of traffic and are used on highways to prevent vehicle crossovers that lead to head-on collisions.



Andrea says that there are several criteria that must be met before a highway’s speed can be increased. For example, the highway’s design must meet the standard for travel at 110km/h’ it must be fully a controlled access highway; it must be a minimum length; and have sufficient spacing between exits. If one or more of these criteria are not met, says Andrea, a highway cannot be posted at 110 km/h.

Given the criteria, it seems unlikely that the Third will be getting any new highways with posted speeds of 110 km/h anytime soon.
