Why were only four bridge crossing alternatives 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 bridge-replacement alternatives by the Federal Aviation Administration and other stakeholders, the following refined bridge-replacement alternatives were evaluated 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 her
