Roadway surface/Traffic: The the Toll Road section is in moderately poor condition, but is easily manageable and traffic is light to nil. Traffic on Hwy 29 is fairly heavy and there are many trucks and boats being towed up the road in the summer, but there is a good bike lane and the road surface is excellent.
