The Manteca City Council has no problem with the $100 million upgrade that Caltrans is planning on making to a 10-mile stretch of Highway 99 that will extend from the 120 Bypass to Arch Road. They just don’t want to foot the $158,000 annual bill that the landscape architect estimates it’ll cost to maintain the $2 million worth of landscaping included in the project for the Lathrop Road and Highway 99 interchange. During a presentation Tuesday night intended to outline the options for the interchange the council was keenly interested in the ideas being presented by a landscape architect assigned to the project.
