The Saint Paul segment of the Gateway Trail from Cayuga Avenue to Arlington Avenue is temporarily detoured along the east side of Interstate 35E, while the DNR re-routes the trail south of Arlington. You’ll see detour signs at Cayuga and Arlington directing you to a paved Saint Paul city trail that parallels the I-35E barrier wall. 

Part of this detour route rises above the freeway for a view sweeping from the downtown Saint Paul skyline, past the domes of the Minnesota State Capitol and Cathedral of Saint Paul, and across the Trout Brook Valley. The valley was long home to the Mdewakanton Dakota; in the later 19th century it was the site of farming and market gardening for the growing city, milling and factories, railroad yards and working class families. In the 1960s the Interstate Highway System brought I-35E through the capital city. From this city trail detour you can get a glimpse of Saint Paul's historic North End and East Side that freeway commuters miss in their cars below.
