Abstract
A truck front section (120) including a grill (128), a hood (121), and a bridge assembly (137) is provided. The grill has a substantially vertical front surface and an upper portion. The hood has an upper panel (121) with a sloping front end disposed adjacent the grill upper portion. The bridge assembly is disposed above the front end of the hood upper panel and has a pair of oppositely disposed upright end members (133) attached to the hood upper panel. The bridge assembly also has a substantially horizontal aerodynamically shaped member (138 and/or 140) attached to the end members. The upper portion of the grill, the front end of the hood upper panel and the bridge assembly cooperatively form a duct generally disposed above the grill. The duct may discharge into a longitudinal channel (112 and/or 114) formed in the upper panel.
