Fir Street Bridge Replacement

PBS served as the owner’s representative to manage the design phase (completed) and construction phase (ongoing) for the replacement of the previous Fir Street bridge (formerly a three-span bridge) crossing Olequa Creek with a new bridge. The previous bridge had significant bank erosion near the east abutment that was undermining the foundations, and had been deemed unsafe and closed to both vehicular and foot traffic. The bridge was replaced by a single-span bridge. The length of the new bridge was extended to move the end abutments away from the top of the bank and out of the 100-year flood zone to reduce flow constrictions and future potential bank instability. The new single-span bridge will not impede high flows nor cause backwater.
