Point of Highway Clarification

In the local newspaper there is an explanation from the New Mexico Department of Transportation that purports to answer a question involving an uneven portion of a recently completed overpass.

Here’s the quote as it appeared in the paper…

”the concrete pavement has a grade break at the ramp gore – where the loop ramp lanes separate from the westbound PDN lanes – which redirects storm water runoff and reduces the amount of drainage that would otherwise cross the loop ramp lanes at that location. The grade break is minimal and is within acceptable tolerance even though it is visible as a driver approaches the ramp. The variation in the concrete pavement addresses a drainage issue that needed to be mitigated while staying within the physical constraints of the bridge, the mainline PDN lanes, and the diverging loop ramp lanes.”

Thanks for the clarification!
