Preliminary designs involve converting 15th Street to a four-lane roadway divided by a raised median that will allow for left turns at median breaks. U-turn movements for eastbound passenger vehicles will be provided at the following five locations:
- ​Minuteman Lane
- North Pierce Street
- Market Street
- Holloman Street
- Brown Street
The proposed median will be grass, but the final treatment (which may include additional landscaping elements) will be coordinated with the City of Washington.
One traffic signal will be relocated from Washington Street to North Pierce Street. Potential new signal locations will be evaluated as part of the project, and new signals could be added along the project corridor.
