Craig also said he saw 17 vehicles go through the traffic light one time at the affected Joppa intersection (Routes 7 and 152), and traffic back-ups are not a unique problem to that area.

"That happens everywhere," he said.

Several callers during the show also expressed concerns about traffic, including how the facility would affect response times from the nearby Joppa-Magnolia fire station.

Four people called into the show, and each mentioned their concerns about increased traffic and public safety issues, in particular with the Joppa-Magnolia fire station. The trash facility will be between the fire station and may residential neighborhoods to the east.

One of the callers, named Michelle, pointed out that Route 7 already backs up when there are accidents on I-95. "I don't see how it can support 400 trucks," she said, adding: "You are going to cut us off from the rest of Harford County."

Another caller, from the Gunpowder neighborhood, raised the question of fire equipment getting through when the transfer station is open.

Craig said the neighborhood has other fire stations, although that one may be more prominent, and the caller pointed out that other connections to Route 7, such as Joppa Farm Road, can't handle most fire trucks because of the low clearance at the CSX railroad overpass.

Craig said he expects there will be some road improvements, mainly creating a shoulder to better accommodate the truck traffic.

He added, however: "Whether they're going to make further improvements down the way would probably not be something the state would recommend," as Route 7 is a state road.

In any case, Craig noted the county still has to complete an environmental assessment of the transfer station site, as well as a traffic study in conjunction with the State Highway Administration.
