The first started in early June at the intersection of Lake City Way and 24th Avenue NE. From the Seattle Department of Transportation:
Pedestrians and bus passengers will soon benefit from improvements now underway near the busy intersection of 24th Avenue Northeast and Lake City Way Northeast. A contractor working for the Seattle Department of Transportation is constructing new sidewalks and other street elements to improve safety, and expects to complete the work in about three months. The project includes sidewalks, a curb bulb, curb ramps, a new crosswalk, an upgraded traffic signal, and improvements to a bus stop and storm drainage, many of which were recommended by the community.
The project at 24th Avenue was identified through the Lake City Way Traffic Safety Project.
The second significant project is happening farther north at the inyersection of Lake City Way and NE 145th Street. It started June 12th. Again, from SDOT:
This project, intended to improve safety for all travelers, includes new curb ramps (southeast and southwest corners), roadway pavement panels, storm drainage improvements and an upgraded traffic signal.
Over the summer, contractors will remove and replace the existing curb ramps, upgrade signal poles and conduct electrical work. During construction, the contractor will reduce lanes, relocate the bus stop and detour pedestrians on an as-needed basis.
The crews will typically work from 7 a.m. to 6 p.m. with possible work on weekends. SDOT expects the project to be completed in mid-August, weather permitting.
