We previously had a nice little discussion about the rise in popularity of roundabouts in the Greater Columbus Area. It sounds like more are on the way:
More roundabouts planned in city
Thursday, January 17, 2008
Roundabouts — circular intersections designed to help control traffic in congested areas — will become more prevalent in Dublin, according to Paul Hammersmith, the city’s director of engineering.
He told council that compared to some intersection designs, roundabouts cost less and seem to be working well in the community.
A study of that area for the city by engineers R.D. Zande & Associates determined the current intersections operate poorly, resulting in congestion and peak-hour delay concerns. Nine options were developed for the two intersections, including two with signalized controls and five using roundabouts.
The recommended option is a two-lane roundabout just above Tullymore that would have modified access at Valley Stream. The cost is estimated at $1.75-million
