Are you talking about the Hwy.66 bridge crossing the French Broad River coming from the I-40 into Sevierville/Pigeon Forge area? A very large walk out ramp has been built out over the river on the North Side just above the Old Lee Greenwood Theater. Another new building is being started in the field just as you cross the river and before you get to the knife building. The large extended ramp will be used for something like a Zip Line or viewing area. I can't tell about a boat ramp.
