Why are only four bridge crossing alternatives being evaluated?
The alternatives initially considered in the screening process included a total of 15 bridge-replacement, transit, freight-movement, and travel-demand-management alternatives. Eleven alternatives were not advanced beyond the first level of screening as they did not address the project purpose and need and project goals. On the basis of the screening evaluations of the initial alternatives considered; input received during outreach meetings; and the later design studies conducted to address the height limitations set for the replacement-bridge alternatives by the FAA and other stakeholders, the following refined bridge-replacement alternatives are being studies in the DEIS: • “New” Alignment South (formerly 6-lane Replacement Bridge – South) • “New” Alignment North (formerly 6-lane Replacement Bridge – North) • “Existing” Alignment South (formerly Twin Replacement Bridges – South) • “Existing” Alignment North (formerly Twin Replacement Bridges – North) Click here for more information ab
