The Variable Speed Limit (VSL) signs that have been under construction along I-76 from Montgomery County to Philadelphia are now active. At first, the signs will remain static while the system undergoes further testing. Once the testing phase is complete the speed limits displayed will change dynamically based on traffic and safety conditions along I-76. Find out more about these signs and how they help with traffic by watching the video.

More information on the VSL signs, including Frequently Asked Questions, can be found here: Variable Speed Limits.
