Note: Monorail officials have proposed up to four miles of single-tracked sections where northbound and southbound trains take turns using the tracks. However, the line's builders are likely to propose less single tracking.

Here are the highlights of the Green Line route, listed by station:

1. Crown Hill: Connects to bus routes at southwest corner of Northwest 85th Street and 15th Avenue Northwest. An overhead switch and two tracks cover the street. No new park-and-ride facilities planned on the route.

2. Northwest 65th Street: On west side of street, across from Ballard High School and close to buildings. Possible single-track construction.

3. Northwest Market Street: Tall station followed by a bridge above the Lake Washington Ship Canal. Housing developers tout access to monorail. Potential connection to a Ballard-to-University line in distant future.

4. Interbay: Site just south of West Dravus Street, placed to avoid QFC parking lot and improve bus access.

Operations center: Seven-acre base would use several switches to shuttle buses onto the mainline. Northwest Center, the current occupant, must relocate 330 staff members and disabled workers to a site near the Duwamish River. Tracks go mostly down center of 15th Avenue West.

5. Elliott Avenue: Serves heavily populated area. Steep terrain will require stairway descent to entrance, or a footbridge. View of Elliott Bay. Tracks continue east via West Harrison Street.

6. Seattle Center: A few steps from KeyArena and retail district. Tracks wind around International Fountain and through monorail gap in the Experience Music Project. The controversial Seattle Center passage was approved 5-4 by the City Council.

7. Fifth and Broad: Fifth Avenue covered by two switches north of Denny Way and two south of Denny, to provide more frequent downtown service.

8. Bell Street: Historic 1962 monorail to be demolished. New tracks built over a widened sidewalk on west side of Fifth. Station at southwest corner of Fifth and Bell, but would not displace the Seattle Glassblowing Studio.

9. Fifth and Stewart: Critics complain midblock site is too far north of retail core, one reason the Downtown Seattle Association now opposes the monorail. A skybridge into Westlake Center may be considered.

10. Pike Place Market: Some landowners want midblock station moved to the more visible corner at Second and Pike. Potential to combine a station with new office or housing tower.

11. Madison: Monorail agency might not acquire Federal Reserve Bank property in time for scheduled monorail opening in 2009. Station near pedestrian bridges to ferry terminal.

12. Yesler: Replaces the "Sinking Ship" parking garage. Pioneer Square neighbors want pedestrian walkways, open space or car parking on leftover parts of the triangular lot.

13. King Street: Adjacent to historic train depot and Sounder commuter rail; two-block walk to light-rail and buses.

14. Safeco Field: Baseball fans board trains from tall platforms, possibly near Royal Brougham Way and the right-center field seats.

15. First and Lander: Serves commuters to Starbucks Center, as well as sports fans coming from buses or their parked cars. Displaces barn-shaped Earthwise vintage home-furnishings store and three other stores. Five right-angle turns through Sodo area slow the trains.

West Seattle Bridge: City transportation director Grace Crunican has questioned the proposal to build single track instead of twin monorail tracks on the bridge deck. Single track would save money but limit capacity.

16. Delridge: Station at Nucor Steel mill is 100 feet high. Good bus and bike access to Alki and Admiral neighborhoods, harder to reach from lower-income Delridge and Westwood areas. Original site south of steel mill dropped because of opposition from neighbors.

17. Avalon: Tracks in center of 35th Avenue Southwest, instead of original route past Huling Brothers auto showroom on Fauntleroy Way. No plan yet to provide safe pedestrian passage across 35th, between station and the West Seattle Stadium.

18. Alaska Junction: Train stop complements proposed eight-story building in heart of reviving crossroads, but trains approach within about 10 feet of new condominiums lining California Avenue Southwest to the south.

19. Morgan Junction: Single tracks on west side of California, with a switch and southern terminus near Southwest Morgan Street.
