Three alternatives to replace an existing two$-$lane highway with a four$-$lane highway that will meet current design sinndards are proposed. The selected alternative will provide a more direct route betwern wo towns that are $12\mathrm{.}0$ miles apart along the existing highway. With each alternation amerating speeds are expected to be at or near the design speed of $60m\frac{i}{h}.$ Develop the scores for each alternative and recommend a preferred alternative for development. The following scoring method, developed by the transportation oversight board, is to be used:
