We placed this tube here to celebrate the opening of this path.
The structure of the bridge was built in sections and once together is about 750 feet in length.

This project is a bicycle / pedestrian bridge over Beltline Highway and its frontage road, located between Todd Drive and Fish Hatchery Road. It includes paved asphalt path approaching the bridge beginning south of the Beltline at Greenway View (the north end of the Cannonball Phase 1 project completed in 2011). The paved path will initially extend approximately 1000 feet north of Beltline. Discussions are under way to extend the path to Fish Hatchery Road shortly after the Phase 3 project has been completed.
This bridge is the key piece of the overall 4+ mile Cannonball Path, a major new commuter route linking areas of Fitchburg and Arbor Hills neighborhood with downtown Madison. The overall Cannonball Path project is a joint effort between Madison and Fitchburg, with land acquisition partially funded by Wisconsin Department of natural Resources. Madison is the lead agency for the Phase 3 project, which will be constructed by WisDOT and partially funded under the SMIP program with Federal Enhancement funds. When completed, the path will connect neighborhoods with parks, schools, major conservancy areas as well as retail, commercial and employment centers. It also connects to the Capital City Trail, Southwest Path, Military Ridge Trail and Badger State Trail, making it a key component of the regional network of paths for recreation as well as transportation.
