FALLON COUNTY, MONTANA
The Plevna Road North Structure project replaced a narrow 100-foot-long timber bridge with a 48-foot-long triple 14’ by 14’ cast-in-place reinforced concrete box culvert. To improve safety and drainage, the existing roadbed and drainage ditches were regraded. To eliminate the burden of traffic having to make an excessive detour around the bridge, the contractor constructed a 24-foot-wide detour near the project site. The detour also acted as a cofferdam to aid in the dewatering of Sandstone Creek. Upon completion of the box culvert, an existing levee located northeast of the box culvert was replaced, and the temporary bypass was removed.
Brosz completed the environmental documentation, design, and construction administration for the project. Brosz’s role consisted of an original topography and legal survey, preliminary and final design, project bidding, right-of-way acquisition assistance, utility coordination, and USACE permitting. Brosz also provided construction administration services which included inspection, surveying, testing, pay applications, and final project close-out.
