Do roads negate the +1 for slopes? The rules say roads negate the value given on the TEC but for a slope it's just +1. It could be argued that going up a slope on a road is 2/3 +1 (For mechanized).
My interpretation is "units moving along a road (including bridges) pay the road movement cost on the Terrain Effect Chart, not the cost of the terrain in the hex nor of the elevation lines crossed" and that's how I develop scenarios for 4th edition.
