But when plans for the extension were removed from Baltimore County's Master Plan in October 2010, the battle against it appeared to be over.
So why was a Gunview Road sign recently installed near the Belair Road and Honeygo Boulevard intersection?
"I immediately called the State Highway Administration district engineer and learned it was put up by SHA officials who were unaware the county has wiped this road off the books," Marks wrote in an email to Patch.
"I personally worked for a decade to defeat the extension and I don't want residents thinking it is somehow back," he wrote.
The sign was removed late last week.
Marks led a campaign against the Gunview Road extension as PHIA president and continued fighting it as a county councilman. State Sen. Kathy Klausmeier and state delegates Joe Boteler, Eric Bromwell and Todd Schuler each sent letters opposing it. Dennis M. Robinson Jr., current PHIA president, has also been an outspoken opponent of the plan.
The extension would have connected several of the streets that extend out of Belair Road in the northwest direction—including Seven Courts Drive, Baker Lane, Kahlston Road and Schroeder Avenue—culminating in a connection at Honeygo Boulevard.
Some referred to it as a mini-beltway around Perry Hall.
The plan would have allowed drivers to access dozens of neighborhoods in the northwest half of Perry Hall without traveling through the busy two-mile stretch of Belair Road. It would also have allowed for the development of a small portion of the Gunpowder Falls State Park and opened many streets up for more housing developments.
