National Highway System (NHS) freight connectors serve as
critical links between the mainline NHS and major intermodal terminals.
A 2000 Federal Highway Administration report to Congress on the condition
and performance of intermodal connectors identified 517 freight-only terminals
composed of ocean and river ports, truck/rail, and pipeline/truck facilities.
In addition to these freight-only terminals, 99 major freight airports
(which handle both passenger and freight) were included in the list of
freight intermodal terminals.
An analysis of highway-rail grade crossings on the federal aid highway system
by the Federal Railroad Administration finds that all categories of highway
users could spend up to $7.8 billion in lost time at grade crossings over
the next 20 years. Auto users could spend 123 million more hours delayed
at crossings and truckers could log an additional 6.6 million hours behind
closed gates in 2022 compared to 2002.
An estimated $300 million annual investment in grade separation over the next 20 years could maintain highway user costs at grade crossings at 2002 levels. A projected annual investment of $450 million would be sufficient to separate all grade crossings on the Federal-aid highway system where estimated highway user costs exceed capital investment requirements. These two investment levels are comparable to the "Maintain User Costs" and "Maximum Economic Investment" scenarios for highways discussed in Chapter 7. Some grade separation improvements are also reflected in the estimates of the Cost to Maintain and Cost to Improve Highways and Bridges presented in Chapter 7.
