Hwy 58 Over Forks + CN

Brown & Co. was retained by Dufferin Construction to provide detailed design services for the rehabilitation of the Highway 58 bridges over Fork's Road and CN Rail. The two structures are each three span steel bridges with concrete decks, with an overall length of approximately 30m. The overall project included full confirmation of the existing sub-structure, review of deterioration of the existing piers, bearing replacement, deck replacement, abutment widening, vertical realignment of the roadway between the structures requiring a substantial increase in fill height and construction phase services.
Brown & Co. developed an initial plan for the design-build project followed by full detailed design of the work based on the owner's "30 %" design drawing. Remedial work design for the piers included assessing the piers for the widened deck, with strengthening required. The rehabilitation work included detailed mark out of concrete replacement at the abutments and piers. The design of new components included design of new wing walls with anchorage to the existing abutments, new semi-integral deck and steel beam design. Brown & Co. were the lead consultants on this work. Our subconsultants were BTE who provided the design for the realigned and widened roadway and Patriot Engineering who provided geotechnical design for the confirmation of the existing foundations and embankment stability and settlement analysis.
