Highway and Bridge Spending Versus Investment Requirements

Transit Capital Spending Versus Investment Requirements

The Timing of Investment

Exhibit 8-13 shows how the investment requirements over the entire 20-year horizon are distributed among each 5-year period. Investments under the Maintain scenario are relatively backloaded, with 54 percent of investment in the latter 10 years. This largely reflects the need for greater capital investments in later years to accommodate transit passenger travel growth. Under the improve scenario, investments in the initial period are equal in the first and last periods. This is due primarily to the larger investment under this scenario during the early period that is necessary to eliminate the initial backlog of deficiencies.
