Business Loop I-5 - Cottonwood

According to Jerry Mullady, there used to be a sign for Route 5 Business along I-5 north at Exit 662 for Bowman Road and Cottonwood. Early 2000s sign replacements omitted the business route reference and signs posted along the 2.8 mile route today reference only historic U.S. 99. Business Loop I-5 through Cottonwood followed Main Street between Exits 662 and 665.
