Evaluation of the Performance of a Press-Lam Timber Bridge: Interim Report, No. 1, Bridge Installation and Load Test

Report No: 78-R2

Published in 1977

About the report:

The report describes the installation and load test of the world's first press-lam timber bridge superstructure. A five-man crew replaced the substandard steel stringer-timber deck superstructure on Rte. 610 over Little Stoney Creek in Shenandoah County with the press-lam superstructure in about four work days, and the road was closed for only eight hours. Results of the load tests conducted two weeks after the 17.5 ft.(5.33 m) span, 2-lane bridge was constructed suggest that the stringer live load distribution specified by AASHTO is conservative. The Research Council will inspect and load test the bridge periodically over a five-year period.
