The purpose of this project is to replace the existing, structurally-deficient and functionally-obsolete

Vrooman Road Bridge (SFN 4337107) over the Grand River, that regularly closes during flood events

with a bridge and roadway facility that meets current design standards and improves existing geometrics

correcting existing roadway geometric deficiencies, while providing a safe, efficient route.

The existing Vrooman Road Bridge (SFN 4337107) is a structurally-deficient and functionally-obsolete

bridge that regularly closes during flood events. The existing roadway approaches to the bridge are

characterized by numerous geometric deficiencies, which can be directly linked to high accident rates at

various points along the roadway. The existing Vrooman Road and SR-84 intersection is characterized by

numerous geometric deficiencies, which can be directly linked to high accident rates at the intersection.

Approved Purpose and Need Statement 9-9-09

• Project would replace existing low-level river crossing with a high level crossing on one of two proposed alignments.

• Improved horizontal and vertical alignments.

• Improved intersection geometry at project termini.
