Bicycle Passport welcomes you to our web-site and the Quest. The mountain pass information is yours to use, but recognize it is not currently being updated. We are disappointed — in the extreme—to report that CDOT & CSP declined our Special Permit request to ride through Eisenhower Tunnel. This followed two years of work and Traffic Engineering studies that demonstrated it could be done safely. We think it is a lousy and discriminatory decision by those State Agencies. Combined with the C-19 pandemic, this is a death knell to our small business, and we are liquidating the Company. We wish you every success in pursuing the Quest — You will see us out there in pursuit of the “41” as well!
