Street crews are planning to lay down white lines on streets where the new River Rail will pass to try to prevent accidents with parked cars. The Eight foot Eight inch wide yellow street cars are to begin passenger service November First, and a test run last week determined that motorists tend to park their cars too far out from the curb and risk having side mirrors and other parts of their vehicles damaged. The 48,000 pound street cars will follow a two and a half mile route through some narrow downtown streets in Little Rock and North Little Rock. Contractors expect to begin painting solid white lines this week along the narrow spots, on Main Street north of Broadway in North Little Rock and on President Clinton Avenue in the River Market District. Vehicles parked across the white lines could be towed or ticketed.
