The speed limit on Fairfax County Parkway has been reduced and will soon be enforced by speed cameras, as construction to widen the major thoroughfare continues.
A speed limit of 45 mph — down from 50 mph — took effect today (Friday), with workers unveiling new signage throughout the work zone from I-66 near Fair Lakes to Route 123 (Ox Road) in Fairfax Station, according to Fairfax County.
