What is the speed limit for the Flex Lane, and can it be increased to 70 mph?
The speed limit is 70 mph for the US-23 Flex Route. The speeds shown above the lanes are advisory speeds or “recommended” speeds based on areas of restricted sight distance when the shoulder is being used as a travel lane. The effectiveness of the advisory speed system is being reviewed and MDOT expects to make some improvements in this area over the next few years. However, it is still unknown whether the 60 mph advisory speed will remain in place whenever the shoulder is open to traffic.
