Only EVERYWHERE :) There is a lot of building going on in Denver in general and roads are no exception! There has been a lot of resurfacing of some of the major streets through Downtown, Cap Hill, Golden Triangle (and probably everywhere else that I don't go too often). Have you driven south on Broadway from Downtown to I-25 lately? Crossing over 6th Ave used to be like a mini roller-coaster, but now it's smooth as can be! It's so nice :) It will be great when they finish the Broadway bridge over Cherry Creek.
There's a ton of construction on 225 and on 36 to accommodate the new light rail lines that are being built. I'm so excited to see new rail lines that I'm glad to sit in traffic for a while, knowing what a vast improvement we're going to see in the next couple of years.
