WILLIAMS COUNTY ROAD 8 BRIDGE AND ROADWAY RECONSTRUCTION

County Road 8 located 9 miles north of Williston, ND, off of US Highway 2 is a busy transportation corridor serving well pads, oil and gas facilities, aggregate pits, a rural school and residents. The reconstruction of this roadway from US Highway 2 to County Road 9 included 3 miles of asphalt pavement reconstruction and road widening, culvert replacement and replacement of the Little Muddy River Bridge as a separate project. Ackerman-Estvold provided overall project management, roadway design, drainage analysis and culvert design, environmental clearance and documentation, agency coordination including NDDOT and FHWA, US Army Corps of Engineer’s Section 404 permitting and the construction management and inspection for Williams County of these two projects.

​

The roadway reconstruction project removed the existing 20’ wide asphalt roadway, widened the roadway, replaced culverts and installed a 28’ wide asphalt roadway. The roadway widening permanently impacted adjacent wetlands and on-site wetland creation mitigated the impacts and helped secure the section 404 permit. The widened roadway allowed the installation of edge and center rumble strips to enhance the overall roadway safety. Construction of this $3.9 million project was completed in 2015 and funded by Williams County.

​

The bridge project replaced the 70’ single span steel I-girder bridge rated as structurally deficient with a new 3-span, 168’ long concrete box beam bridge. Williams County utilized the NDDOT’s federal aid bridge replacement program to help fund this project, requiring FHWA project approval. Ackerman-Estvold completed the environmental document approved by FHWA as well as the roadway and guardrail design in cooperation with the structural subconsultant. The bridge was constructed and opened in 2015 with final project completion in 2016 at a cost of $1.6 million.
