ODOT is focused on preservation first, and has consistently reported that 90%+ of its funding has gone to maintenance activities over the last few years. Safety is another major priority in their spending, improving intersections, etc.
Locals still want expansion projects, however, whether it be the Portsmouth Bypass, Cleveland Opportunity Corridor, new interchanges, etc. Political forces mean these projects still occur here and there, but I don't think we're seeing new highway development (like a bunch of new limited access corridors) as we once did.
ODOT/TRAC has been asking local communities to bring more local dollars to the table to make these projects happen. When you see an expansion project, even on the state system, there's a good chance the funding is broader than ODOT. Many new/expanded interchanges are substantially local funded. Mainline interstate widening is usually just ODOT, but many times these occur with larger preservation/reconstruction projects (Columbus or Cleveland innerbelt rebuild, reconstruction of 71 thru Morrow County, etc.).
The interstates/innerbelts through most cities have or are being completely rebuilt. These projects are incredibly expensive, and many times have a positive impact on the city streets, such as the caps in Columbus. I don't think we'll see these improvements continue without additional state funding such as the proposed gas tax.
