TRAFFIC ALERT: MSD roadway closure on River Road at Seventh and West Washington streets delayed until further notice

LOUISVILLE, KY — The section of River Road at Seventh and West Washington streets that was scheduled to close beginning tomorrow, May 14, will remain open until further notice. In the last few days, MSD has determined potential alternatives that may minimize the length of the closure and/or mitigate the closure. MSD wants to thoroughly analyze these new alternatives before closing this vital roadway. More information will be provided as plans develop.

Background

MSD plans to build an underground connection point to the Waterway Protection Tunnel in the area of River Road, Seventh and West Washington streets. The connection is called a a “drop shaft,” which is a vertical structure, similar to a manhole that will drop approximately 200 feet in the ground. When complete, the drop shaft will move wastewater and rainwater from the existing sewer system into the tunnel. This prevents the combined waters from overflowing into the Ohio River.
MSD had plans to build the shaft in the grassy median at 7th and Washington streets. This would have required a nearly two-year closure of the roadway in this area for the safety of the public and workers. We are now exploring options that could accomplish this same goal with much less disruption to the public, businesses and attractions in the area.

MSD’s larger effort to reduce overflows

The Waterway Protection Tunnel is part of MSD’s larger effort to prevent sewage from overflowing into Louisville’s waterways. MSD’s basins and the tunnel will capture rainwater and sewage during rain events. The underground storage areas keep the mixture of rainwater and sewage until the rain subsides. Then, the mixture is
gradually released back into the sewer system for treatment.

The Waterway Protection Tunnel will eliminate 22 combined sewer overflow points that put 351 million gallons of sewage and rainfall in a typical year into the South Fork of Beargrass Creek and the Ohio River.

By 2020, MSD will capture and treat 98 percent of the combined sewer overflow volume in a typical year of rain. Combined sewer overflows will then total only 343 million gallons in a typical year. That is substantially less than the two- to nearly six-billion gallons of combined sewer overflows per year that MSD has reported in recent years.

FAQ – River Road/Seventh/W Washington

WHEN WILL YOU WORK?
Usually, work will be conducted during normal working hours: Monday through Friday during daylight hours. However, there may be select weekends or overnight work necessary to maintain our construction schedule.

WHAT IS A DROP SHAFT?
A drop shaft is a vertical structure, similar to a manhole, that is used to convey combined sewer overflow from the existing sewer system to the tunnel system.

DOES IT INCLUDE BLASTING OR DYNAMITE?
HOW FAR DOWN WILL YOU DIG?
No blasting will occur with the construction of the drop shaft. The drop shaft at Seventh and Washington Streets is approximately 205-feet deep. About 40-feet of soil will be removed through traditional construction excavation methods. The rock, approximately 165-feet, will be removed via a raised bore method, which means it will be excavated from inside the tunnel up toward the ground surface.

WHY WILL THE WORK AT THIS SITE TAKE SO LONG?
The construction activities at this site involve the relocation of existing utilities and construction of a drop shaft that is 205-feet deep.

WHY DO YOU HAVE TO CLOSE THE ROAD?
The road has to be closed due to:
1) The location of the drop shaft. 2) Staging and storage of equipment and materials. 3) To ensure a safe working area that allows the maneuver of equipment and materials.

WHY CAN’T YOU OPEN THE ROAD AT THE END OF THE WORKDAY?
Sections of pavement must be removed for the relocation of existing utilities and construction of the drop shaft. The roadway will not be suitable for driving during construction.

DID YOU CONSIDER OTHER ALTERNATIVES?
Multiple locations were considered during the design phase of the project. This location was chosen due to the proximity to the existing sanitary sewer system, and available working area adjacent to the site.

WILL IT BE NOISY?
Noise will be typical of a traditional construction site.

IS IT GOING TO SMELL?
No, the flow entering the system at this location is a mixture of wastewater that is highly diluted with stormwater.
