Rock O’ The Range is Oregon’s only covered span located east of the Cascade Range and one of the few covered bridges built in the second half of the twentieth century. It represents an architectural style that is unique to Oregon.
In developing a parcel of land north of Bend, Oregon, William Bowers needed to build an access across Swalley Canal to his property. He was inspired by Lane County’s Goodpasture Bridge and decided that his bridge should be covered. Bowers instructed Maurice Olson, a local contractor, to construct the bridge according to a picture of a covered bridge found on a calendar.
Specially ordered Douglas Fir timbers were placed on concrete pilings to support both the dead weight of the bridge and the live load of passing traffic. Although small timbers were added to strengthen the span, technically a truss span is not used. Cedar siding, a shingle roof and windows were added refinements. The bridge was completed in 1963 for about $4500.
Bowers has dedicated the bridge to the public. Maintenance costs for the bridge are borne by landowners who use the bridge for access to their properties.
