US 12/18 and Fish Hatchery Rd. Interchange Improvements - Need/purpose
Why is this project needed?
Project will address traffic
operations and safety issues identified for US 12/18 (Beltline) and US 12/18 and Fish Hatchery Rd. Interchange in the Madison Beltline
Operational Needs Assessment report from 2009.
Issues identified in the report:
Backups on off ramp from US 12/18 (Beltline) westbound to Fish
Hatchery Rd. extend past the exit and
onto the Beltline.
Crash rates are more than three times the Madison Beltline study average at the Fish Hatchery
Rd. northbound on ramp
loop merging onto
US 12/18 (Beltline) westbound.
On ramp loop from Fish Hatchery Rd. northbound to US 12/18
(Beltline) westbound is too tight
thus it does not
meet design standards.
Emil St./Ann St. intersection on
Fish Hatchery Rd. is too close to the ramp intersection and could
cause potential backups.
No sidewalk along the west side of Fish Hatchery Rd.
difficulty for bicycles and pedestrians to safely navigate through
the existing ramp intersections.
Correct deficiencies listed above
Improving operations and safety along US 12/18 (Beltline) and Fish Hatchery Rd.
Allow the facility to serve as a safe transportation link in
the transportation system with an adequate level of service for
motorists while accommodating the needs of other travel modes
along Fish Hatchery Rd., such as bicyclists, pedestrians, and
