Keokee Street Alternatives

OPTION 1

OPTION 1: BICYCLE BOULEVARD

Option 1 along Keokee Street consists of a bicycle boulevard treatment. Bicycle boulevards are streets designed to maintain or induce low motorized traffic volumes and speeds that allow bicyclists to comfortably ride in the travel lane along with vehicular traffic. These are often designated as bicycle routes. Some of the typical treatments include bicycle sharrow markings indicating that the bicyclists are encouraged to use the travel lane and traffic calming treatments such as speed humps, curb extensions, and median islands.

OPTION 2

OPTION 2: ADVISORY BICYCLE SHOULDERS

Option 2 adds advisory bicycle shoulders in place of on-street parking. Advisory bicycle shoulders are a new treatment type in the United States. They create usable shoulders for bicyclists on a roadway that is otherwise too narrow to accommodate bicycle lanes. On roadways with advisory bicycle shoulders, motorists travel in the center, single, two-way travel lane and may need to encroach into the advisory shoulder space to pass oncoming vehicles. The images below explain how bicycle advisory shoulders function.
