NW Express Lanes shortened rush hour: GDOT

The Northwest Corridor Express Lanes through Cobb and Cherokee counties continue to exceed expectations, reducing the I-75/575 corridor’s rush hour by more than an hour since opening last fall, the Georgia Department of Transportation said.

The 29.7 miles of tolled, reversible express lanes opened last September and have seen more than 4.2 million trips at travel speeds 30 percent faster than in the general purpose lanes, GDOT said. The express lanes utilize “dynamic pricing,” with higher peak-period tolls and lower tolls off-peak.

“The Northwest Corridor Express Lanes have created compelling new commute options for motorists and transit users, who often described them as ‘life changing,’” said GDOT Commissioner Russell R. McMurry. Drivers in non-toll lanes also benefited, with average rush hour speeds in some cases doubling from 20 to 40 mph.

GDOT has proposed similar express toll lanes across the top end of I-285 in Cobb, North Fulton and DeKalb counties, and for Ga. 400 in North Fulton and Forsyth counties.
