Since 2004, the Mountain Express has actively provided transportation service from Rhododendron to Sandy, serving Zigzag, Welches, Wemme and Brightwood in between. The bus currently costs $2 per person per ride.
It connects with the Sandy Area Metro bus system, which connects with the regionwide TriMet transit system.
The Mountain Express had about 1,000 riders a month in 2005, according to the Villages at Mount Hood, the quasi-governmental organization in charge of the program. Ridership demographics indicate strong usage by seniors, the disabled, and afterschool youth.
