Instability of retaining wall shuts down lane on brand new street

Moncton officials are grappling this morning with a potentially significant problem that has developed in a new stretch of highway that just recently opened to the public.

truck drives in a single lane where the sidewalk and the exterior northbound lane of Mapleton Road, between Trinity Drive and Frampton Lane are closed.
The closure is a result of some slope instability in the retaining wall that runs parallel to this part of Mapleton Road. The lane and sidewalk will remain closed until the retaining wall is fixed. Only about one month after first opening the newly rebuilt section of Mapleton Road, the outside northbound lane of the four-lane street, between Trinity Drive and Frampton Lane, has been closed, as well as the sidewalk that runs beside it.
"The closure is a result of some instability in the retaining wall that runs parallel to this part of Mapleton Road," City of Moncton spokesman Paul Thomson says. A fix is likely to take "at least" three weeks, the city says.
In the meantime, the outside lane on the northbound stretch, located just north of where Wheeler Boulevard exits onto Mapleton and onto Trinity Drive, is blocked off by traffic cones and the sidewalk is closed to pedestrians as well. There is no sidewalk on the other side of Mapleton Road.
That stretch of highway receives heavy usage, especially during morning and evening rush hours and during this time of year as Christmas shoppers make their way to the popular shopping area.
While the road opened only last month after being completely rebuilt and expanded to four lanes, the retaining wall accommodates several new retail outlets that are in the process of being built. It is not known how the instability of the wall might affect that busy construction area. No one was working there yesterday.
Engineers working at the new fashion retail outlet notified the city of some undue settling of the slope that separates Mapleton Road from the under-construction retail centre. That prompted the city to close one lane of the road, plus the sidewalk, Thomson says. The retaining wall and slope will be observed for a period of time to gauge the extent of the problem.
"The city is erring on the side of caution," Thomson said last night.
"It's unfortunate but public safety is paramount."
It is "premature" to start discussing who will pay for repairs, if any are necessary, he said.
The problem is not with the road, but with the sloped land and the wall that retains it. However, any undue settling could badly affect the road and sidewalk above it.
Motorists proceeding north of Mapleton Road, or turning northward onto Mapleton from Wheeler Boulevard or Trinity Drive, are advised to watch out for the closed lane. Pedestrians are urged to exercise caution if they have to walk there and drivers should watch out for people on foot who might be walking along the side of the road.
The new section of Mapleton is but the first phase of the busy street's transformation from a bumpy two-lane road into a major entry point into the city. By this time next year, the plan is to have the road twinned all the way northward to the Trans-Canada Highway (Hwy. 2) and to double the size of the Mapleton Road overpass over Wheeler Boulevard to six lanes from three.
That work is expected to get under way in May.
