Downtown Dayton Street Conversion Project
In 2003, MVRPC, in partnership with the City of Dayton and Downtown Dayton Partnership commissioned a feasibility study to assess the traffic-related effects of converting the existing one-way street grid system in downtown Dayton, Ohio, to a two-way street grid system. The proposed conversion to a two-way street grid system would coincide with the proposed improvements to I-75 and State Route (SR) 4. The traffic planning implications of the proposed conversion to a two-way street grid system are focused on the following issues:
- The ability of the proposed two-way street grid system to operate at acceptable Levels of Service during the daily AM and PM peak hours;
- The effects of converting to a two-way street grid system on the on-street parking supply; and
- The effects of converting to a two-way street grid system on pedestrians in downtown Dayton.
The final Feasibility Study is available for more information.
In the fall of 2005, MVRPC initiated a Phase II contract with TetraTech, Inc. for the preliminary engineering phase for this project. This work, the development of a functional plan to improve mobility throughout downtown Dayton, was completed in December 2007.
Stakeholder meeting summaries
The Summary and Schedule (
:93 kb) for the preliminary engineering has more information.
Four separate configurations of two-way service were developed, and each was analyzed for operations under future-year traffic demand. A one-way (no-build) scenario was also modeled for current and future years. By way of summary, the report concludes that the conversion of the existing one-way street grid system to the proposed two-way street grid system would operate at acceptable Levels of Service. There would be increases in congestion under each of the two-way systems, as well as varying degrees of loss of parking spaces, but the level of delay was found to be acceptable. Two-way operation could also enhance traffic flow between I-75 and downtown Dayton, and between US-35 and downtown Dayton.

The Miami Valley Regional Planning Commission (MVRPC) hosted a Public Participation Meeting on April 5, 2007 to present for comment the preferred alternative to change selected routes in Downtown Dayton from one-way travel to two-way travel. The materials presented on preferred alternative are available for review below.

The environmental clearance process for Alternative 4 (preferred alternative) was completed in December 2007. The next step is for the City of Dayton to begin final design on the plans. Construction funds are currently scheduled for SFY2009.
