Contract provided for the improvement of the North Road area near Leavenworth, WA by widening, excavating 16,000 cubic yards of material, drilling and blasting large, embedded granite, replacing a 176’ 10’ diameter multi-plate culvert in Chumstick Creek with 32’ wide 136’6” long pre-stressed concrete girdered bridge, lowering the roadway grade at the BNSF Railroad trestle and constructing a walkway through the trestle, placing new surfacing, improving drainage, installing guardrail and traffic barriers. Work also included the construction of an infiltration ponds and drywells. To proceed with the new bridge build, a temporary access road was put in place on the west side of the ravine (Chumstick Creek) which required de-watering and re-routing of creek; Hence, two coffer dams were constructed (one on up end, one on down end of temporary road over creek), two 8”diesel pumps were placed and ran 24 hours per day, for three weeks, and pumped water up the bank at a 50’ vertical and released the water 250’ up the creek until the construction of the bridge (abutments, setting of girders, decking) was completed. Temporary road made up of 5,000 cubic yards of material was excavated and removed along with the entire 10’ diameter culvert pipe. To complete the project, a new creek bottom was put in place beneath the new bridge and the site was restored to its natural habitat with new landscaping, plantings, trees, etc.. All work was in accordance with the WDFW in-water work specifications.
