The City’s construction project on East Lake Sammamish Parkway is nearing the end of the first week of full road closure. The Parkway will reopen the morning of Aug. 22. This extension from the planned closure will allow new water and sewer mains to be installed while avoiding traffic queuing.

This week, the City’s contractor has been able to safely construct water and sewer bypass systems, install the stream bypass and road dewatering systems, prepare trench boxes for the culvert shoring, and start the deep excavation for the culvert.

Puget Sound Energy (PSE) has scheduled work on Saturday, Aug. 11 to remove overhead power on East Lake Sammamish Parkway that would conflict with the safe crane operation to install the culvert. No power outages or interruption of power are expected with PSE work.

The City’s contractor worked on Sunday, Aug. 12 from 9 a.m.-6 p.m. They removed existing peat material under East Lake Sammamish Parkway that is unsuitable for supporting the culvert. They may also work on Sunday, Aug. 19 to complete required work during the road closure.
