Fred Gottemoeller would like to see an overpass for buses only built alongside the existing pedestrian bridge over U.S. 29, just north of the Broken Land Parkway interchange.
He said he and a colleague have been working on a proposal for such a project and will present their suggestions within a few weeks.
At public input meetings this spring, General Growth Properties Inc. representatives discussed the possibility of a full, above-grade interchange near the southern end of Lake Kittamaqundi to carry vehicular traffic between Columbia Town Center and Oakland Mills.
Gottemoeller said he attended the April 28 unveiling of the draft master plan for the proposed revitalization of Columbia's Town Center, and was impressed by the concepts of a walkable downtown and expanded use of mass transit.
Not only would this overpass give preference to buses, it would provide an opportunity to build a "memorable" landmark for the city of Columbia, he said.
