Expect changes on northbound state Route 900 as construction starts this week on a trail connector across Interstate 90.
The initial phase calls for the northbound high-occupancy vehicle lane on state Route 900 to temporarily close. The contractor, Issaquah-based C. A. Carey Corp., also plans to narrow the driving lanes on state Route 900 between the interstate’s eastbound off-ramp and westbound on-ramp.
City engineers expect the project to prompt future closures of the HOV lane on the westbound on-ramp.
City Council members picked a contractor for the nearly $5.3 million project last month. The city has steered about $341,000 to the project, and received grants to cover the rest of the tab.
Plans call for a separate 12-foot-wide pedestrian bridge across the westbound I-90 on-ramps and modifications to the existing state Route 900 overpass to install a 10-foot-wide pedestrian crossing.
The project aims complete a trail about 1,600 feet long, between the end of the state Route 900 boardwalk at the eastbound I-90 off-ramp on the south side of the interstate, and the Sammamish Trail on the north.
