If you're referring to Exits 1-4, that's an active construction zone, not terribly surprising. It will all be cleaned up once it's complete.
That construction zone looks half abandoned and underfunded. But that one area is no excuse for the entire Beltline to be an overgrown mess, as is the case at all of the I-540 exit ramps too.
Other cities don't have ubiquitous 6 foot tall weeds on every ramp and growing up through the guardrail. Kill the weeds.
Raleigh usually has among the most beautiful freeways (I-40 East from the airport) and at the same time has some of the sloppiest, visually cluttered arterials with sagging traffic signals etc. The dichotomy is unfortunate.
My idea is to let residents and businesses donate money for nearby intersection aesthetic upgrades, since NCDOT places Mast-arm signals at the lowest level of priority.
Every other state and Charlotte are replacing span-wire signals with metal poles at a rapid pace, and I'm scared that Raleigh won't ever tidy-up intersections to look better like Cary has so close by.
