EXIT 211 A A 2,125 ft equal tangent vertical curve joins a +2.2% grade to-3.6% grade. The PVI of the vertical curve is station 55+21 at elevation 150 ft. To meet MUTCD standards for advance guidance, an overhead sign structure must be placed at station 55+85. The bottom of the sign will be 18 ft above the roadway surface (more than the recommended 16.5 feet to accommodate larger trucks that use the roadway). WEST 56 Utopia Botlom of sign 18...
