Notes
The US 74 interchange with I 95 is half closed. The north half of the diamond is open, while the south side ramps have been removed to build the I 74/US 74 interchange.
The Cooper River Bridge (US 17) is awesome. It is a double cable stayed bridge, the first I have personally driven across.
Clinched the current version of the Carolina Bays Parkway ( Future I 73/74 ). There are no Future signs to be seen.
The transition from SC 9 South to US 17 North is a surface road connection by way of SC 90. Unlike the transition to US 17 South, which is just a freeway level merge.
The second bridge to Oak Island is under construction. There was a whole line of construction vehicles along the right of way from the NC 211 and Midway Road intersection. On Oak Island, the waterway access at the north end of Middleton is now a holding area for bridge supports. Yacht Drive is open through the construction. The north half of the block of Middleton between Oak Island Drive and Yacht Drive is completely leveled. It appears this block will be the approach to the bridge. It is not clear whether Yacht Drive will go under the bridge or if it will be cut there.
I got a clear view of an old shield gantry on the ramp taking I 40 West onto I 440 Inner Beltline. The gantry has US 70 EAST and NC 50 SOUTH. There was a time when current US 70 through Garner was signed US 70 Business. During that period, US 70 and NC 50 were routed up I 40 to I 440 to the current US 70/401/NC 50 interchange. The gantry on the ramp in question should have been US 70 West and NC 50 North. The current gantry is clearly wrong. I need to get a picture.
