Master Transportation Plan Task 4: Gap Analysis and Needs Network
• The number of lanes in 2050 is lower or equal to 2, as higher capacity corridors are less feasible to be widened further. • Only considering off-system roadways. • Include only corridors that are more than 2 miles long. • For locations where multiple parallel facilities were identified, consider the longest among them. • ROW feasibility for most of the corridor. The existing ROW was reviewed and compared to the potential increase of capacity, assuming 11-foot lanes and 6 additional feet on both sides. If few segments (<10 percent of the corridor) did not have enough ROW, a high-level feasibility analysis was done considering natural boundaries and land use. Figure 8 shows the resulting roadway corridors that met the criteria for capacity improvement. For these corridors, a one-lane capacity increase is proposed to improve congestion, up to a maximum of six-lane corridors. The details of the corridors and suggested lane configurations are specified in Table 4 .
