Highway Economic Analysis Calculations The following example, adapted $4\mathrm{.}5$ from Ref. $6,$ illustrates application of some of the data and procedures presented earlier in the chapter.

A highway agency is considering eliminating $($straightening$)$ an $S-$shaped curve on a multilane highway. Total construction cost for the improvement is estimated at $$2$ million and will be incurred at the inception of the project. Annual maintenance costs are anticipated to be $$2,000$ less after the improvement because the elimination of the curve reduces pavement and guardrail damage.
