Tips for Bike Commuters During MAX Steel Bridge Service Interruption August 2-24
The Steel Bridge will be closed to cars, buses and MAX trains August 2-24, 2008, as crews connect existing tracks to the new MAX Green Line tracks on 5th and 6th avenues. Shuttle buses will be carrying MAX riders across the river between the Old Town/Chinatown Station and the Rose Quarter/Convention Center stations, via the Burnside Bridge. The lower deck of the Steel Bridge will remain open to bikes and pedestrians.
If you bring your bike on MAX…
Please plan ahead and allow extra time for your trips.
We strongly encourage you to ride your bike across the bridge rather than using the shuttle bus to reach the MAX stop on the other side of the river. (The ride across the bridge will take about 7 minutes compared to 15 minutes on the bus shuttle.) Follow the signs to the bike route on the lower deck of the bridge. Stay on the marked path, and be considerate of pedestrians.
Riding MAX from the east side
Yellow Line riders
Get off at Interstate/Rose Quarter station and ride your bike to your destination. You can follow the signs to the Steel Bridge and re-board MAX at Old/Town Chinatown Station. Or, stay on the Esplanade to cross the Hawthorne Bridge.
Blue/Red Line riders
Get off at Rose Quarter TC and walk your bike along the marked path to Interstate Avenue. Then, follow the signs to ride across the Steel Bridge and re-board MAX at Old/Town Chinatown Station.
Riding MAX from the west side
Yellow Line riders
There will be no Yellow Line service on the west side of the river. Bike to Old Town and follow the signs on Davis Street to cross the Steel Bridge and connect with northbound Yellow Line trains at Interstate/Rose Quarter Station or eastbound Blue and Red line trains at Rose Quarter TC.
Blue/Red Line riders
Please allow extra time for your trips. Fewer MAX trains will be running between Old Town and Hillsboro. Get off at Old Town/Chinatown Station, follow the signs on Davis Street to cross the Steel Bridge and connect with eastbound Blue and Red line trains at Rose Quarter TC or northbound Yellow Line trains at Interstate/Rose Quarter Station.
* Travel outside of rush hour to avoid crowding. The farther away from 8 a.m. or 5 p.m. you make your trip, the more room there is on the trains.
* Try parking your bike at a MAX platform instead of bringing it on the train. Additional bike parking will be available during this time.
