This site will show you a marker on the exact halfway point along I-95:

If you zoom in, there aren't really many towns right at the midpoint, maybe Saint George (South Carolina)?
Otherwise, if you have enough time for a detour off the highway, you could find a lot more interesting stops along the coast, possibly Summerville or maybe even Charleston if you can afford to alter your route to hit the beach:
