This north-south thoroughfare in central St. Paul is a monument to how government ineptitude can work for you. For 50 years, officials plotted to use the slender Ayd Mill valley as a freeway connector joining I-94 and I-35E. Neighborhood opposition stymied their every move. So a decade ago, St. Paul finally jerry-rigged a solution: adding connections from Ayd Mill to Selby Avenue and 35E. The valley makes it a somewhat hidden street, but only for the better. In a town short on uncongested north-south byways, it offers a traffic-free gateway to the delights of lower West Seventh Street and the suburbs beyond.
