After leaving Federal Way, the Sound Transit Board’s Preferred Alternative route, Preferred Fife alternative, follows I-5 until it begins to gradually curve at Porter Way to briefly align and then cross over SR 99, also called Pacific Highway East. The route then curves northwest until it runs east-west, just south of 12th Street East. The route then enters the elevated Fife Station on the west side of 59th Avenue East, which is part of the preferred alternative. Federal regulations and guidance for floodplain management require us to consider alternatives found outside of the floodplain. We’re now proposing to study two more potential station options—the Fife 54th Span Station Option and Fife 54th-West Station Option—outside of the designated floodplain. For the routes we are studying in Fife and from the Preferred Fife alternative, one route would curve slightly north toward 12th Street East and cross over 54th Avenue East to enter Fife 54th-West Station with a southwest slanted orientation. Second, from the Preferred Fife alternative, the other route curves slightly south toward 15th Street East to enter Fife 54th Span Station, which spans 54th Avenue East just north of 15th Street East. After exiting the station, we are studying three route alternatives that travel west. The Fife Pacific Highway elevated route exits the station westward and crosses over 54th Avenue East before crossing and transitioning to the south side of Pacific Highway near Willow Road. This elevated route continues along the south side of Pacific Highway until it reaches 34th Avenue East where it transitions south to the north side of I-5 on its way to the Tacoma segment of the project. We are also studying a route called Fife Median. This route is similar to the Fife Pacific Highway route; however, it is elevated in the median of Pacific Highway until it reaches 34th Avenue East where it transitions south to the north side of I-5 on its way to the Tacoma segment of the project. Lastly, we are studying the Fife I-5 route. This route exits Fife Station westward and crosses over 54th Avenue East and veers south, crossing over Pacific Highway to gradually curve to align with the north side of I-5 on its way to the Tacoma segment of the project. All of these routes alternatives converge back to the preferred alternative route that crosses the Puyallup River en route to Tacoma.

The start of Tacoma Dome Link Extension is at the end of the Federal Way Link Extension at the Federal Way Transit Center. From there, the Sound Transit’s Board Preferred Alternative route, Preferred SF Enchanted Parkway, gradually curves to run alongside the I-5 corridor. After the elevated route crosses S 344th Street, it travels through some commercial properties before an elevated crossing of S 348th Street. It then crosses over Enchanted Parkway to serve the Board’s Preferred Alternative, SF Enchanted Parkway Station, elevated at Enchanted Parkway and S 352nd Street. We are also studying an elevated SF 352nd Span Station Option, which is called a “span” station option because it has entrances on both sides of the intersection. After that, the route follows Enchanted Parkway until it curves back toward the I-5 corridor on its way to Fife via Milton. An additional route alternative we are studying is SF I-5. This route follows the same alignment as the preferred alternative up until S 344th Street, where it continues south along I-5 until it reaches another elevated station alternative, SF I-5 Station, located at the current Jet Chevrolet auto dealership. After exiting the station, the route continues south along I-5 to Fife via Milton. We are studying a potential additional route alternative in South Federal Way called SF Pacific Highway. This route exits a station at Enchanted Parkway and S 352nd Street and curves southwest until aligning with SR 99. The route continues along SR 99 until the curve in I-5 near Milton where it rejoins the preferred alternative. We’re also exploring two potential station locations for study in the vicinity of the SF Enchanted Parkway Station that would serve the Pacific Highway route. We are also studying both garage and surface parking options at each of the South Federal Way station alternatives.

Map showing the Tacoma Dome Link Extension project. The project starts at the Federal Way Transit Center with a route traveling south with a station area in South Federal Way in the vicinity of Federal Way Crossings shopping center. The route continues south and curves west to enter a station area in Fife. The route continues west to cross over the Puyallup River to enter two station areas, one near Portland Avenue and one near the Tacoma Dome, where the project ends.

This route exits a station at Enchanted Parkway and S 352nd Street and curves southwest until aligning with SR 99.

From Fife, the route crosses the Puyallup River just north of I-5. The span over the river will either be a higher, clear span option or a lower span that includes piers in the Puyallup River. After the river crossing, the route enters the elevated Preferred Alternative Portland Avenue Station, located on the east side of Portland Avenue near East 26th Street. After exiting the station, the route crosses over the Sounder Tracks and is elevated over East 25th Street. We are also studying an elevated Portland Avenue Span Station Option, which is called a “span” station option because it has entrances on both sides of Portland Avenue, just north of E 26th Street. After exiting the station, the route crosses over the Sounder Tracks and is elevated over East 25th Street. The route from the Portland Avenue station area to the Tacoma Dome station area depends on the station alternative selected in both of the station areas. Watch and listen to the Tacoma Dome video for more details.

The Sound Transit Board’s Preferred Alternative route, called Tacoma 25th Street – West, leaves westward from the Portland Avenue Station then crosses over the Sounder tracks and East L Street, remaining elevated over East 25th Street entering the elevated Tacoma 25th Street – West Station located between East G and East D Streets, adjacent to the transit park-and-ride garage on E 25th Street. We are also studying a route called Tacoma 25th Street-East, which also exits westward from the Portland Avenue Station and crosses over the Sounder tracks and East L Street and is elevated over East 25th Street. This route enters the elevated Tacoma 25th Street-East Station located on East 25th Street, just east of East G Street. Another route we are studying is Tacoma 26th Street. This route exits westward from the Portland Avenue Station and follows the Sounder tracks crossing under East L Street then gradually curves south to be elevated over East 26th Street where it enters the elevated Tacoma 26th Street Station located at the intersection of East D Street and East 26th Street. The station would span the intersection with entrances on both sides of the street. Lastly, we are studying a route called Tacoma Close to Sounder. This route exits the Portland Avenue Station and aligns with the south side of the Sounder train corridor. The route runs under East L Street before crossing over the Sounder tracks and enters the elevated Tacoma Close to Sounder Station, which is located within the footprint of the eastern portion of Freighthouse Square west of East G Street.
