History and Signage Information History and Signage Information

This route was defined in 1960.

Per Tom Fearer, the original alignment of US 99 ran from the Route 99 Freeway west Frontage Road westward on County Sign Route J9/French Camp Road to El Dorado Street in French Camp. Originally US 99 had an elongated alignment south of Stockton. US 99 southbound entered Stockton on Wilson Way where turned west on Charter Way and south on McKinley Avenue. US 99 continued south to French Camp via El Dorado Road and onto French Camp Road where it met US 48 at Harlan Road. US 99 continued southeast on French Camp Road to Main Street in Manteca. This alignment appears to have been in use until 1929. Likely starting in 1929, US 99 split into US 99E at Mariposa Road/LRN 4 and US 99W at Charter Way/LRN 5. US 99E largely followed the current Route 99 freeway south to Manteca. US 99W followed McKinley Avenue, El Dorado Street and French Camp Road south to French Camp. From French Camp, US 99W continued south to Lanthrop on Harlan Road and Manthey Road where it met the new terminus with US 48. At Yosemite Avenue/LRN 66, the route of US 99W turned eastward towards US 99E in Manteca.
