Table 1 - Benefit
IMAGE 2 - Cost
The table below summarizes the cost of each alternative. The single point urban interchange is our most expensive alternative due to high pavement and structural items cost. While the most cost effective is the Partial Cloverleaf alternative.

IMAGE 3 - Project Benefit/Cost Analysis
When comparing the total benefit and total cost of each alternative the benefit/cost ratio is obtained. The partial cloverleaf alternative has the highest B/C ratio followed closely by Little League Tee.

BENEFIT
COST ANALYSIS
IMAGE 1 - Benefit
The benefit is derived from comparing the design life costs of the no build versus the design life costs of each alternative. The difference in costs is what's consider the benefit of each alternative. Essentially, the benefit is the amount of money saved from switching to an alternative as opposed to keeping the no build option. Factors taken into consideration were delay time, fuel consumption, and carbon emissions. The alternative with the highest benefit is the Par-clo (Partial Cloverleaf) as shown in table 1.
