Progress is being made on the Highway 7 Three Lane project! Existing pavement has been removed where needed, and an embankment has been built along the road in preparation for the third lane. The area where the new lane will eventually be poured is beginning to take shape along the road, as seen in the photo below.

Workers have also installed water drainage measures to prevent water from building up under roadways and damaging the pavement. A modified subbase has been laid down. The subbase, shown in the photo below, is made of gravel and allows water to flow out from under the pavement, into the subdrains. Subdrains, which were also installed this week, carry water away from the road.
Workers are expected to be on site next week to begin paving an asphalt base course. This base course provides strength and stability for the road.
