Comprehensive Land Techno­logies (CLT) continues its work on the bridge replacement on the Causeway at the Head of the Lake.

In its weekly report to China Town Manager Dennis Heath, they reported they have completely exposed the timber mat and have begun installation of the stone mat. Because of overnight rain, the water level upstream had risen and the area needed to be pumped down.

The stone mat was observed and appeared that things were being constructed in accordance with the design drawings.

The limits of the timber mat were discovered, and it was only found within the footprint of the old bridge. It was decided the stone mat needed to be two feet thick in all areas outside the timber mat. A surveyor was brought in to verify elevations and layout limits of the excavation.

According to CLT Superintendent Brooks Dow, erosion and sedimentation controls continued to function in the same manner as before. CLT was pumping water from the excavation into the sediment basin and filtered water was sheeting back into the pond on the upstream side of the bridge.

Excavation work continued on the Causeway at the Head of China Lake to prepare the subgrade to continue the build out of the stone mat. (Contributed photo)
