In January 2017, the city of Vancouver began an improvement project on Northeast 18th Street between Four Seasons Lane and Northeast 136th Avenue. Construction is expected to occur primarily between 7 a.m. and 5 p.m on weekdays, but may be extended to weekends and as late as 8 p.m. The work may cause delays at times on Route 177. C-VAN may also need to use alternate routes due to construction activity.

Construction is expected to be complete in early 2018.
