 In Duanesburg, the section of Route 30 the limousine was traveling becomes hillier as the road veers east into the Schoharie Creek valley and undulates more.Just north of the blinker at NY 7, the highway reaches a height of land at in elevation, from which it descends almost in the next two miles (3.2 km) to its junction with NY 30A.As it crosses over Interstate 88, signs direct trucks to use Route 7 instead.
