Source: Section of Cobb Road closed by sinkhole in Trigg County | WHOP 1230 AM | News Radio A section of Cobb Road in northern Trigg County is closed due to the formation of a sinkhole between the 4 and 5 mile marker not far from the Brushy Grove Creek Bridge. The Kentucky Transportation Cabinet says it’s about two miles west of the Cerulean Community and a little less than a mile east of the Trigg-Caldwell County Line. A contract mowing crew was working along the right-of-way Wednesday when one of the tractors broke through the surface. On investigation, the crew discovered a hole created by the tractor at the edge of the pavement was about 8 feet deep and extended out under the pavement about 10 feet or more. Cobb Road is closed and barricaded at the site as state officials develop a repair plan. The Cabinet says while sinkholes are not uncommon in areas with karst topography, this appears to be one of the larger holes to develop in recent years. Depending on the depth of the sinkhole, Cobb Road could be closed at the site for several days or more.
Source: Kentucky seeks action against WVa gov's coal companies - LEXINGTON, Ky. (AP) — Regulators want the family of West Virginia Gov. Jim Justice to pay a penalty and follow through on a promise to fix environmental problems at eastern Kentucky coal mines. The Kentucky Energy and Environment Cabinet asked a circuit judge this week to enforce an agreement over reclamation violations against Justice; his son, Jay Justice; and several family coal companies. It included a $3 million penalty, plus interest, the Lexington Herald-Leader reported. In a motion filed in Franklin County, the Kentucky agency wants to revoke five permits at Justice-company mines and seize money that had previously been posted for reclamation. The motion seeks to force the companies to fix the site violations and block any new or amended permits until then. The Justices and their companies “have been provided many second chances to meet their permit obligations and time and again have failed,” the motion said. Lexington attorney Richard Getty, who represents the family, said the state’s request was “unnecessarily severe.” Justice has said many of the violations were inherited when he acquired the properties. The companies admitted to hundreds of reclamation violations in eastern Kentucky in 2014 and agreed to monitor water quality, fix drainage problems, stabilize landslides, clean out sediment ponds and eliminate highwalls at dozens of mines. After the companies missed a deadline to fix the issues, the state sued in 2015 to enforce the earlier agreement. A new settlement was reached in 2019 setting deadlines to complete reclamation work at five mines, along with other requirements. Last year, Justice's companies agreed to pay more than $5 million for thousands of mine safety violations in a civil case brought by prosecutors in Virginia on behalf of the U.S. Department of Labor and the Mine Safety and [...]

Companies shell out $10,000 to $20,000 for a geotechnical and subsurface investigation before construction.The process isn't necessarily feasible for everyday people.However, a Western Kentucky University Geotechnical Engineer developed a device to detect what's happening beneath your feet.Karst terrain covers more than half of Kentucky. Karst sinkholes form when the bedrock of the Earth is slowly worn away by erosion.[SLIDESHOW: How karst sinkholes form]Under the top soil is a layer called the overburden. Under that is bedrock, which may seem tough and solid, but it's actually filled with cracks and crevices water is constantly seeping through and infiltrating. As the water erodes the bedrock, the overburden starts to fall down into the space left behind. Years later, all that's left is a thin layer and the potential for a sinkhole to open up.However, if there's a slab over the surface you may not know there's a problem until it's too late. That's why Matt Dettman developed MSEDS, short for Mechanical Sinkhole Early Detection System. Dettman is a WKU Associate Professor of Civil Engineering [...]
2/10/2016 Upcoming Tunneling Projects CALIFORNIA Laguna Beach 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. Los Angeles 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 Rides in Griffith Park, just north of the I-5 Griffith Park On/Off Ramps (I-5 Shaft Site) east [...]
https://www.youtube.com/watch?v=26r9MpVATsI Today's "Walk the Bridge" event attracted tens of thousands of people. The Louisville-Southern Indiana Ohio River Bridges Project addresses cross-river transportation needs in Louisville, Kentucky and Southern Indiana and will result in safer travel, less congestion and improved access to destinations in the region. LOUISVILLE, Ky. – Governor Steve Beshear announced that the new Ohio River bridge between Kentucky and Indiana in downtown Louisville will be named the Abraham Lincoln Bridge – connecting, as it does, the states of Lincoln’s birth and raising. “Lincoln led our nation through its bloodiest and greatest constitutional and political crisis – the American Civil War,” Gov. Beshear said. “But at the end of that national trauma, we remained a ‘United’ States of America. It’s therefore fitting that we honor Lincoln’s legacy with a bridge that further unites Kentucky, where he was born, with Indiana then Illinois, where he emigrated as a youth and grew to adulthood.” Kentucky and Indiana jointly are building the bridges project to improve cross-river mobility between Louisville and Southern Indiana. The project also includes construction of a new bridge eight miles upriver, connecting Prospect, Kentucky, and Utica, Indiana.
