Looking at the picture you provided, a few suggestions:
Add at least a small gap between the bridge ramp and the buildings next to it, the gap should probably end in a wall or some-such, it's just a building would never share a wall with a highway.
I'd also recommend extending out the ramp leading up to the bridge, since it looks quite steep. If you want to get fancy with it, you could have a small side road on each side of the ramp with an underpass connecting them beneath the ramp.
But looking cool so far!
