Transportation Leaders Announce Traffic Plans With Indefinite Closing of Sherman Minton Bridge

LOUISVILLE, Ky. (September 10, 2011) — The public should expect long traffic delays, especially during peak rush hours, with the indefinite closing of the Sherman Minton Bridge between Louisville and New Albany, transportation leaders on both sides of the Ohio River announced today.

Mayor Greg Fischer, joined by officials from the Indiana Department of Transportation and the Kentucky Transportation Cabinet, announced the following items to help alleviate some of the congestion.

• When possible, it’s important for people to avoid peak travel times in the morning and evening.

• People should carpool – three or four to a vehicle – to help reduce the number of automobiles on the interstates.

• People should stagger their commute times – going to work early and leaving early or going to work late and leaving late.

• Companies should be as flexible as possible and allow employees to work from home…to telecommute…and to have staggered arrival and departure times.

• If possible, when traveling within Louisville, drivers should use surface streets and stay off the interstate. This will cause more congestion on side streets, however it will help alleviate cars on the interstates.

A detailed traffic management plan is being developed to ensure that congestion is alleviated as much as possible for as long as the bridge is closed. As soon as feasible, lanes of the Second Street Bridge will be converted to reverse lanes, though that is unlikely to occur before Monday.

When the reverse lanes are in place, there will be three southbound lanes and one northbound lane during the morning commute. For the evening commute, that will reverse, with three northbound lanes and one southbound lane. Traffic flow on the Kennedy Bridge (I-65) will remain normal.

Where possible, exit ramps along I-65 in Southern Indiana will be widened from one to two lanes to help traffic flow.

In addition, officials from the Transit Authority of River City are working with the two states to develop plans to use public transit to move people by buses across the river.

The Sherman Minton Bridge which carries I-64 over the Ohio River west of downtown Louisville was closed for about three hours this morning after being struck by a barge. An inspection found that the bridge had only suffered superficial damage.

The Courier-Journal has posted a video of the Ohio River flowing past a barge lodged against the K&I bridge: Courier-Journal: Video: The Ohio River at the K&I Bridge (April 13, 2006 )

The railroad bridge is now operated by Norfolk Southern. At one time, it also carried automobile vehicle traffic.

The construction phase of a project to widen the southern portion of the Danville by-pass to four lanes may begin this spring. Bid will be let for the project is month.

Mount Washington is home to a bit of signing oddity: instead of the old route of US 31E being marked "Business US 31E" it is marked as "US 31EX." Photos of this oddly signed route can be found here.

The Kentucky Transportation Cabinet Division of Planning is conducting a study concerning a new route connecting KY 33 north of Danville to US 150 east of Danville in Boyle County.

The Danville Advocate Messenger  reported on July 29, 2003 that work to rebuild the US 150 Danville viaduct should be complete by September 15 and that it should re-open to traffic by September 1. The viaduct originally opened in 1949. Years of salt and traffic have caused the concrete to deteriorate, and the Transportation Cabinet is replacing the viaduct as a preventative measure. The viaduct will retain its original arched architecture.

Danny Lewis has created a website with information about the Cedar Creek Lake project  in Lincoln County. The recent creation of the lake involved the rebuilding of US 150 and KY 1770. Danny's site includes maps and photographs. Some pictures show part of the Old US 150 being slowly submerged as the lake level rises.

The KYTC Division of Planning has posted information concerning a scoping study  to determine a route for a connector route between US 150 and I-75 in Lincoln and Rockcastle Counties.

From www.kytc.state.ky.us/news/stanfordribbon-cutting.htm :

Frankfort, Ky. - Governor Paul E. Patton will be joined by representatives of Lincoln County, the Kentucky Transportation Cabinet and the Kentucky Department of Fish & Wildlife for a ribbon-cutting ceremony to dedicate the new Cedar Lake Dam and US 150 reconstruction on Wednesday, September 4th, 2002 at 2:45 p.m. ET.

The ribbon-cutting ceremony will take place on the dam located approximately 6.5 miles west of Stanford on US 150.

A newly rebuilt six-mile section of US 150 in Lincoln County between Stanford and Crab Orchard has recently opened to traffic. The new road includes a dam on Cedar Creek. The project is expected to be completed soon and a dedication ceremony has been tentatively scheduled Sept. 4.

The above article also mentions a project on KY 501 to eliminate two 90 degree turns and a project to correct a rock fall hazard on US 27 in Lincoln County. The rock fall hazard was caused by people looking for the mineral millerite.
