Throughout January and February, carpenters and ironworkers continued working on the remaining edge girder sections of the Wasco Viaduct. Crews are now performing post-tensioning activities to reinforce the concrete before the last four girders are installed on the south side of the pergola structure. The viaducts on the north and south side of the structure are expected to be complete this spring. When complete, the Wasco Viaduct will be nearly 2,000 feet long.
