MSD budgets $200 million for Ohio River Tunnel project – WDRB 41 Louisville News
The Metropolitan Sewer District is budgeting $200 million for the Ohio River Tunnel project to improve water quality in Louisville.
LOUISVILLE, Ky. (WDRB) – The Metropolitan Sewer District is budgeting $200 million for the Ohio River Tunnel project to improve water quality in Louisville.
According to Jacob Mathis, an MSD engineer and manager of this project, just a tenth-of-an-inch of rain can overwhelm parts of the sewer system in the district, sending stormwater and drainage straight into the Ohio River or Beargrass Creek.
“In a typical year, there’d be four billion gallons of sewage released into these waterways,” Mathis said.
In hopes to reduce sewer drainage across the country, the federal government is requiring communities to find ways to mitigate the damage by Dec. 31, 2020. If Louisville does not meet the deadline, the government could enforce fines or penalties.
In response, MSD engineers devised a plan of three new basins in three different neighborhoods to store overflow. But there were concerns over how much that could interrupt construction, business and daily life.
MSD decided to take a different route and came up with the Ohio River Tunnel project.
“This project is one of the first of its kind in Louisville or even the state of Kentucky,” Mathis said.
Engineers describe it as being on the same level and magnitude as the Ohio River bridges undertaking. But this project is intended to be out of sight, out of mind.
“There will be less disruption to the community itself with traffic impacts, economic impacts,” Mathis said. “We won’t disturb the big economic corridor along Main Street.”
The tunnel will start underneath what will be the western part of Waterfront Park near 13th and Rowan Streets. It’ll head east underneath the Ohio River towards I-64. At the Second Street Bridge, the tunnel […]

Tunnel Stabilization and Sewer Pipeline Replacement
Approved by the South Coast Water District Board of Directors in 2010 and the City of Laguna Beach in late 2013, the Tunnel Stabilization & Sewer Pipeline Replacement Project (Tunnel Project) is a 100-year solution to protect the environment, local economies and neighboring communities. The project comprises two key components:
- Tunnel Stabilization: The District will enlarge the size of the tunnel from an average of 6 to 9 ft. This will ensure safer working conditions and greater access for future pipeline maintenance and repair. Permanent shotcrete lining and steel supports will be installed at several locations where required, replacing rotten timber supports and removal of loose rock that currently exist.
- Pipeline Replacement: The District will install a new 24-in. pipeline throughout the tunnel. The current pipeline – also 24 in. in diameter – will be encased in concrete, but preserved for redundancy and emergency use.
The cost to repair the tunnel is estimated at approximately $90 million and will be funded through low-interest state loans, grants and the District’s general fund. Shortlisted tunnel contractors announcement was anticipated for 2014-2015 with request for bids expected in 2015 and NTP in 2015-2016.

The North East Interceptor Sewer (NEIS) Phase 2A
The North East Interceptor Sewer (NEIS) Phase 2A project is currently the northern extension of the NEIS Phase 1 project. The project will construct approximately 3.03 miles of 8-ft diameter sewer in tunnel and associated structures. The sewer will be constructed from the Division St. Shaft site, near the intersection of San Fernando Road and Cazador Street and terminate at the northern overflow parking lot for the Pony and Train […]
I-65 construction south of Indy tests commuters’ patience
Trips from Southport to southern Johnson County can take up to an hour longer
Southside commuters are swerving, merging and yielding a lot for road construction this summer — and there’s little relief in sight.
From Southport Road to Edinburgh and beyond, concrete testing barricades and orange traffic barrels on Interstate 65 have led drivers through myriad lane shifts and closures, adding precious time to rush-hour commutes, as the highway and bridges are rebuilt or repaired.
Alternative routes, including portions of U.S. 31, also are being revamped.
“There aren’t too many areas (of I-65) where we don’t have construction testing and inspection going on right now,” said Indiana Department of Transportation spokesman Harry Maginity. “If you are driving from Indianapolis to Louisville (Ky.), you are going to see a lot of it all year.”
The biggest projects are on I-65 around Greenwood where about 63,000 cars travel both ways each day. Heavy machinery in the blocked-off medians and on bridges has made space in the travel lanes tight and twisting. Combined with reduced speeds, the journey in and out of Indianapolis can add more than hour of travel time for a trip between Southport and Edinburgh.
“Our drivers plan that a trip from I-465 on the […]
