The options for Homestead Road included such improvements as bicycle lanes, sidewalks, paved shoulders, medians and roundabouts.
The aldermen also discussed whether Homestead Road should be a two-, three-, or four-lane road.
"The (Transportation Advisory) Board is comfortable with any of these alternatives," said Dale McKeel, Carrboro's transportation planner.
The project overall covers the area between High School Road and Airport Road, with the portion between High School Road and Rogers Road falling under Carrboro's jurisdiction.
Projected cost for the development is $7.2 million.
Carrboro has favored one specific option, Alternative Five, since 1993. But Mayor Mike Nelson said he would be willing to support Alternative One, favored by the North Carolina Department of Transportation and the TAB.
The two options differ in that Alternative One advocates a three-lane road, and Alternative Five would have two lanes.
Although the aldermen debated the merits of both alternatives, they ultimately voted 6-0 in favor of Alternative One.
Chris van Hasselt, who sits on the TAB, highlighted the positive aspects of Alternative One.
