On June 1 King County will close the ELST through the end of the year for the George Davis Creek culvert replacement project. The location is midway between NE Inglewood Hill Rd and Louis Thompson Rd NE.
The trail will be completely severed during construction. Riders will have to detour to the adjacent East Lake Sammammish Parkway, if it too is not closed. A large number of permanent routes are affected.
According to King County, there will not be a bicycle detour. Typically this means no accommodation will be made for bikes on the road, such as a coned-off lane or wayfinding detour signs.
The culvert under East Lake Sammammish Parkway will also be replaced. The status of the Parkway during construction is unclear. Official messaging has been inconsistent. The latest verbal information an SIR member obtained from the City of Sammammish is that the road will remain open. Likely there will be delays at the construction zone.
Presuming the Parkway remains open, riders can detour on the Parkway. We do not know exactly where the north and south ends of the closure will be, so right now cannot recommend where to exit to the Parkway and later return to the trail. Keep in mind property owners adjacent to the trail are jealous of their private roads and driveways.
In the event the Parkway is entirely closed, riders will have to climb and descend Louis Thompson and Inglewood Hill Rds along with detoured car traffic. In this case, routes not using the ELST will be more attractive.
Stay tuned.
