Traffic Shifts, Interchange Designs Advance Across US, Canada

Several major traffic infrastructure projects across the U.S. and Canada are underway or planned to alleviate congestion and improve travel times. In Tennessee, the Department of Transportation is shifting traffic on Interstate 40 near Nashville International Airport onto its final alignment, requiring temporary lane and ramp closures over a weekend. In Alberta, Canada, new traffic patterns and lane shifts are being implemented at the Highway 1A and 22 interchange in Cochrane, including a new roundabout and temporary ramps, with ongoing adjustments expected throughout the summer. In Deerfield Beach, Florida, a new interchange design will allow I-95 drivers to bypass local traffic signals via overpasses, potentially reducing peak-hour travel times by up to 14 minutes. Meanwhile, in Texas, the expansion of Highway 46 between New Braunfels and Seguin aims to transform it into a four to six-lane overpass to ease growing congestion, though funding and construction timelines remain uncertain. These projects highlight regional efforts to address traffic bottlenecks and improve commuter experiences amid increasing development and population growth.
