California's attorney general is suing to stop a $200 million extension of a southern Orange County toll road.



The Orange County Register reports that Kamala Harris sued last month to block a 5 ½-mile extension of State Route 241.



The suit claims the toll road agency violated state environmental law in approving the project.



It calls the extension a dead-end "road to nowhere" and claims its real purpose is to pave the way for a 16-mile extension linking 241 to Interstate 5 near the San Diego County line.



The California Coastal Commission has rejected the longer extension.



The Foothill-Eastern Transportation Corridor Agency contends the small extension is a stand-alone project. Spokeswoman Lori Olin says the agency hasn't seen the suit and can't comment.
