Mythology is cast aside, and the worst fears of commuters using the year-old intersection of Eisenhower Boulevard and Madison Avenue have been dispelled.
City traffic engineers who have warily tracked the traffic through the “continuous-flow” intersection (CFI) for the past year have the numbers on their side. “There was some level of urban myth about increased accidents there,” said city engineer Tom Knostman, the manager of the CFI project. “Our goal from the beginning was to move the traffic safely, and we’ve accomplished that.”
The intersection is one of the city’s most notorious bottlenecks. Delays on turns from Madison onto Eisenhower, and long waits at stoplights on Eisenhower, had been dogging drivers for years.
But the imported CFI solution, previously installed in Utah and Louisiana, has solved the problem.
Tweaks to the design have been needed: A merge lane taking traffic from Eisenhower to northbound Madison now has a red or flashing-yellow light to guide traffic.
