Surface Transportation Matters (Motor Vehicles and Railroad) <br /> <br />Most of the roadways identified as requiring improvements will <br />need to be improved in the future, regardless of whether or <br />not the PHA builds the Bayport facility. These required <br />improvements are addressed in the no-action alternative. <br /> <br />The need for roadway improvements in most of the study area <br />would be triggered by the projected increases in "background <br />traffic" (trips not associated with facility). This does not <br />include the widening of Port Road from two lanes to four <br />lanes, or ramp improvements (flyovers) between State Highway <br />146 and Port Road. <br /> <br />. <br /> <br />The need for improvements along SH 146 would be accelerated as <br />a result of the Bayport project. A comparison of the required <br />improvements at full build-out in the year 2025 indicates that <br />one additional freeway larye would be needed in each direction <br />on SH 146. The comparison also indicates that the Bayport site <br />would require the least amount of lane mile construction <br />compared to the alternatives. <br /> <br />Table 3.5-53 <br />Comparative Total of Lane Miles Required Per Alternative <br /> <br />Year <br /> <br /> Alternative 2005 2015 2025 <br /> ----------- ---- <br />Bayport 2 16 82 <br />Pelican Island 1 40 99 <br />Spillmans Island 9 16 100 <br />Shoal Point/Bayport 1 21 105 <br />Upper San Jacinto Bay/Bayport. 4 22 111 <br />Shoal Point 1 15 127 <br />Cumulative Scenario 17 30 166 <br />Cedar Point 9 62 184 <br />No Action Alternative 132 186 229 <br /> <br />... <br /> <br />The PHA's main function is to provide, operate, and maintain <br />waterways and marine facilities for cargo and passenger ships. <br />The PHA does not build roads outside of its facilities <br />(responsibility of cities, county, or state).
