1st Ave NE street improvements 

When the project is complete, the street will include a new two-way protected bike lane (PBL) between NE 92nd St and NE 103rd St, along the west side of the street. A PBL separates bikes from motor vehicle traffic lanes by using planters, curbs, and/or parked cars as barriers. PBLs also improve safety for riders and make riding a bike a pleasant and practical way to get around. At NE 103rd St, people biking will use the crosswalk to access the east side of the street, where a multi-use path or widened sidewalk will continue north to Northgate Way (see map below).
