Historic Sites of Manitoba: Concrete Bowstring Arch Bridge No. 367 (La Salle River, RM of Portage la Prairie)

Known locally as “The Rainbow Bridge,” this 50-foot concrete bowstring arch bridge over the La Salle River in the Rural Municipality of Portage la Prairie, near Newton (SE27-11-5W) and the former railway siding of Gervais, was built by William Newman & Company using Plan 367. Construction was completed in October 1919 at a total cost of slightly over $7,000, borne equally by the municipal and provincial governments.
