Great question. I'll tell you what's most on my mind right now, because I just finished listening to a press conference about a new report on the impact of the redistribution of military employees under BRAC this year:
We need road and transit solutions for Fort Belvoir and the Mark Center. VA transportation secretary Connaughton announced two infrastructure plans last week: Add HOT lanes on I-95 and build a new HOV ramp at Seminary Road for the Mark Center. These need to be fully funded, but I'd want to make sure that we've funding new park and ride areas and more bus service in the process.
Meanwhile, a big part of Virginia's current problem isn't just the slow starts on new stuff. Virginia needs more money to maintain what it already has. So I'd spend a lot more on maintenance.
Many of my other fixes would be un-spectacular. I'd spend more on signal timing, building new turn lanes, adding sidewalks so people could safely walk short distances, rather than taking their cars.
