  • Long Island Sound Bridge, from William Floyd Pkwy to New Haven, CT, or

Notes:

  1. Each of the above options might be further enhanced if construction of an intermodal rail-truck terminal within central Long Island could divert a significant number of long-haul truck shipments onto rail. This would be particularly true if those shipments would otherwise be carried by trucks on the highway system during peak periods. The market potential for this peak period freight diversion must be carefully explored before an estimate can be made. The LITP2000 study team is working closely with another study team (Cross Harbor Freight Study) to make these estimates. As appropriate, this will be evaluated carefully during subsequent LITP2000 testing.
  2. Bicycle and Pedestrian travel improvements will also enhance each of the options. The effects of bicycle and pedestrian travel improvements on managing traffic congestion are very difficult to measure technically. Therefore, appropriate recommendations from the LITP2000 Subcommittee on Special Travel Needs will be advanced as improvements to Long Island's quality of life.
  3. Intelligent Transportation System (ITS) treatments will be added during the Tier II level testing, which will begin in the Fall. ITS treatments will include ramp metering on all entry ramps to expressways and parkways and coordinated traffic signal systems, as appropriate and feasible.
