Project update – May 2015

Installation of Phase 1 of the Central Area Neighborhood Greenway began the week of February 23. Phase 1 runs between E. John Street and S. Jackson Street along 21st Avenue E, 22nd Avenue E, and 25th Avenue S. Crews will begin work at E Yesler Way and 25th Avenue South and work their way north to East John Street and 21st Avenue East. Installation elements include:

  • Bicycle pavement markings
  • Stop signs on all streets crossing the greenway
  • Flashing beacons for pedestrians and bicyclists at arterial crossings: 25th Avenue S and E Yesler Way; 25th Avenue S and E Cherry Street
  • Enhanced pedestrian traffic signal at 22nd Avenue E and E Union
  • Approximately one speed hump per block on the route

This work will necessitate some temporary residential street closures, on-street parking restrictions, pedestrian and cyclist detours, and some light construction noise. Access to businesses and residences will be maintained except when temporary restrictions are necessary. Normal work hours will be 7 AM to 4 PM. Installation is expected to be complete in late Spring 2015.

Residential Street Restrictions Begin

Until Friday, May 22, northbound access to 22nd Avenue from E Union Street will be closed as crews install curb ramps and create foundations for a new pedestrian signal. Drivers are detoured to westbound E. Union Street, to northbound 21st Avenue, to E. Pine Street. During this time, local access on southbound 22nd Avenue will be maintained, but access to E Union Street from 22nd Avenue will be restricted.

On Tuesday, May 26, crews will move to the south side of Union Street for curb ramp and foundation work, and access to southbound 22nd Avenue from E Union Street will be restricted. Drivers will be detoured using eastbound E Union Street, southbound 23rd Avenue, and westbound E Marion Street. During this time, local access on northbound 22nd Avenue south of Union will be maintained, but access to E Union Street from 22nd Avenue will be restricted.

Neighborhood greenways are residential streets made safer and calmer for people of all ages and abilities to walk and ride bikes. Small improvements to streets with already low car volumes and speeds add up to a big difference. Greenways can provide access to schools, trails, parks, transit, and neighborhood businesses. They can be especially beneficial for families, children and seniors who might find these routes more comfortable than busier nearby streets. Local access to homes along neighborhood greenways is always preserved, and there are usually minimal, if any, changes to on-street parking. Visit our neighborhood greenways home page to learn more.

Project Description

The Central Area Neighborhood Greenway will run on residential streets adjacent to 23rd Avenue between E. Roanoke Street on the north and Rainier Avenue S. on the south. The Seattle Department of Transportation (SDOT) selected the greenways route with the help of extensive community input gathered at open houses, drop-in sessions, presentations, and briefings. The full route selected is shown on the map at right.

For Phase 1 of the greenway (between S. Jackson and E. John streets), SDOT evaluated four potential routes on the east and west sides of 23rd Avenue for the greenway. With the help of community input, a combination of the previously reviewed routes was ultimately chosen. This hybrid route offers the best features of the considered routes and avoids many of the potential problems.

The Phase 1 hybrid route will run from S. Jackson St. north on 25th/26th avenues. It will turn west at E. Columbia Street, providing a new signalized crossing for bikes and pedestrians. Then the route will go up 22nd Avenue to E. Madison Street, where it will cross over to 21st Avenue and continue north to E. John St.

Potential features of all phases of the greenway include:

  • Pavement markings and signage to alert motorists to expect people bicycling
  • Improved crossings to make it easier for pedestrians and people on bicycles to cross
  • Way-finding to let people know where and how far away the neighborhood destinations are located
  • Median islands, traffic circles, curb bulbs and speed humps to help keep speeds low and drivers from using neighborhood streets to avoid main streets.

Project Schedule

The Central Area Neighborhood Greenway will be implemented in phases. Phase 1 will be installed first. Installation work will begin the week of February 23, 2015, and is expected to be complete in late Spring 2015. Phase 2 and Phase 3 (the south and north ends of the greenway, respectively) will be implemented in late 2015.
