To improve traffic flow and relieve congestion at the SR 429/CR 535 interchange, the Central Florida Expressway Authority (CFX) is building new ramps to and from Stoneybrook West Parkway. This work, occurring nearly a mile south of the SR 429/CR 535 interchange, includes a new exit ramp from southbound SR 429 to Stoneybrook West Parkway and a new entrance ramp from Stoneybrook West Parkway to northbound SR 429. Auxiliary, or merge, lanes and All-Electronic Tolling (AET, allows payment by E-PASS, other accepted transponders, or Pay By Plate) are being added as well. Drivers with an E-PASS or other accepted electronic transponders will save on Pay By Plate charges. The work began in mid-February 2020 and is expected to last approximately eight months.
During construction, motorists can expect night-time lane closures on SR 429 and Stoneybrook West Parkway to accommodate work crews. Most work is planned during the day, although there likely also will be some night work.
