Purpose and Need• The purpose of the South Bridge project is to

provide a critical second route between SH 82 and the western side of the Roaring Fork River in the southern Glenwood Springs area.

• This new route would improve emergency evacuation, emergency service access, and local land use access.

• This second route would respond to the previous 2005 Congressional earmark for the Glenwood Springs South Bridge (new, off system bridge), Public Law 109-59, 109th Congress.

Project Needs• Emergency evacuation needs include:

– Increased local capacity to support both emergency vehicle ingress and evacuation egress.

– Improved redundancy to reduce emergency service provider travel times and reduce the likelihood of a catastrophic occurrence where residents and visitors could be stranded if the existing primary access route is cut off.

• General transportation access needs include:

– Reasonable access options to limit temporary closures due to natural hazards and accidents.

Project Goals• Minimize environmental impacts to scenic, aesthetic,

historic, and natural resources

• Provide a project that is in harmony with the community

• Provide a practical and financially realistic alternative

• Minimize private property impacts• Safely accommodate traffic on area roadways

• Provide an alternative that is consistent with local plans, regional plans, and current studies

• Provide a design that encourages multi-modal traveland does not preclude future multi-modal alternatives in the study area
