An Elon University poll of 422 Mecklenburg County adults on various Charlotte area issues show that close to 75% of Mecklenburg residents prefer the completion of Interstate 485 as the region's top transportation priority. 21% of those surveyed preferred the upgrading of Independence Blvd. 73% of respondents said the I-485 loop should be finished first. The survey was taken between September 16-20; and the margin of error is +/- 4.9 percent. On another hot Charlotte issue - the expansion of rail transit, 44.8% prefer the building of a commuter rail line paralleling Interstate 77 to Lake Norman first. The light-rail (Lynx) expansion to the northeast and UNC-Charlotte was the top rail priority of 36.5% of those polled.
