The Colorado Street Bridge also known as Bridge L-8803 is a masonry and brick arch bridge in Saint Paul, Minnesota's West Side neighborhood. It is 58 feet (18 m) wide and consists of a single oblique span of 70 feet 6 inches (21.49 m)[2] that was built with the arch courses running parallel to the abutments, leading to a weaker structure than other skew arch construction methods,[3] known as a false skew arch.[4] It was designed in 1888 by Andreas W. Munster of the Saint Paul Engineer's Office[2] and is now restricted to pedestrian traffic.[5]
