Miami Valley Roads

Our Miami Valley roadways are essential corridors that link our neighborhoods, workplaces and places we go to enjoy the bountiful amenities in our Region. The Miami Valley Regional Planning Commission wants to help make getting wherever you are going a little bit easier.

MVRPC created this website to provide all of the latest updates on major highway construction projects, bridge replacements and road construction detours throughout the Region. It also provides user-friendly access to route planning tools, ridesharing resources and other ideas to reduce congestion and prevent air pollution.

You can rely on to be the go-to source for full details and the most recent updates on these projects, including great ways that you can adjust your commute to save time, money and stress.

There are major improvements planned for the U.S. 35 corridor in both Greene and Montgomery Counties in the coming years. 

Montgomery County - ODOT District 8

In Montgomery County, construction is currently underway and will continue until late this year on the U.S. 35-Smithville Road interchange project which will remove the northbound Smithville Road to the westbound U.S. 35 flyover ramp structure. A new access will be constructed and will tie in with the existing southbound Smithville Road to westbound U.S. 35 ramp. An additional westbound U.S. 35 lane and concrete median will be constructed to accommodate additional ramp traffic. The project will also include work on the bridge carrying Smithville Road over U.S. 35, including removing the raised island to allow for a left-turn lane and an overlay of the bridge deck and cross frames installed to unify the two structures.

Greene County - ODOT District 8

In Greene County, ODOT will construct two new, innovative intersections called Superstreets in an effort to improve congestion and safety at the intersections of U.S. 35 at 48 /Factory Road and U.S. 35 at Orchard Lane. The majority of heavy construction is scheduled to begin in the spring of 2020 and completed by late 2022. In addition to these major improvements, there are several other maintenance and smaller scale projects taking place in the U.S. 35 corridor in the coming years.
