The city of Sammamish is closing 212th Way Southeast, also known as Snake Hill Road, due to new cracks appearing along the edge of the road, the city announced Thursday.

“Out of an abundance of caution, the city has decided to close the road until further notice,” the city stated on its website.

City engineers had noticed the new cracks and signs of subsiding soil following an inspection on Wednesday. The city stated the cracks and soil issues are on the western edge of the steep and winding road, where the shoulder abruptly falls.

City crews had placed cones next to the vulnerable areas and put up signs on Wednesday encouraging drivers to proceed with caution.

The city stated it may install special signals and reopen a single lane of the road early next week, though such actions would depend on the results of further inspections.

The city of Sammamish is expecting to close Snake Hill Road for several months later this year for improvements to the hillside corridor.
