Just got back from the opening ceremony. Typical political stuff, governor, both senators, the congresswoman, fed and state bureaucrats. The project manager (who is a friend of mine and is retiring next week) got a flag and a scroll. The bands from the two high schools involved (Winfield and Point Pleasant). Some Veteran's Day acknowledgement. Took about 40 minutes.
Ceremony was at the Plantation Road at-grade crossing, which is about 2 miles north of the former south end. Probably about 200 folks there, many band parents.
Waited around another 40 and was allowed to follow the governor and the cop cars up to the north end and then turn around and come back. Road, all asphalt, is in perfect shape, for now. Only a couple of minor at grade intersections, and a few driveway permit connections to private land.
They really are not quite done. The southbound lanes will open for real later today. This will allow the final work to remove the weird connection to the old road at the former north end, which should be done by the end of next week,
To answer the signage question, northbound the exit is signed "WV 817 - WV 62 -Buffalo - Eleanor" southbound is simply WV 62 - Buffalo - Eleanor" No use of the word "TO" and no mention of the bridge's route number. Also no signage for the Toyota plant, which you can get a view of southbound about a mile north of the exit. If you take exit signage points you to "WV 62". There is some reworking of the interchange between the old US 35 (now WV 817), the access road to the ramps, and the bridge, but that will probably be done next spring.
