  • SR 18/Snoqualmie Parkway on-ramp to eastbound I-90: The ramp will close from 9 p.m. Monday, March 10, to 5 a.m. Tuesday, March 11. A signed detour will use westbound I-90 and loop around at Preston/Fall City (exit 22) to eastbound I-90.

SR 18/Snoqualmie Parkway will be reduced to a single lane with flaggers alternating traffic under the I-90 bridges from 9 p.m. Thursday, March 13, to 4:30 a.m. Friday, March 14.
  • Eastbound I-90 off-ramp to SR 18/Snoqualmie Parkway: The ramp will close from 9 p.m. Wednesday, March 12, to 5 a.m. Thursday, March 13.
