Horsehead Resources officially opened its new 1.4 mile inter-plant road that should ease truck traffic on Delaware Avenue in Palmerton and help the company provide better control to trucks inside the plant. The $1.3 million paved roadway begins at the site of the old iron bridge near Route 248 and travels to the company's sample room in the east plant. Over 150 trucks are expected to be brought off Delaware Avenue because of the opening.
