LOUISVILLE, KY. (WDRB) -- Blasting begins later this week on the tunnel approach to the east end bridge.  That blasting will impact traffic from time to time during the next couple of years.

The busy intersection of U.S. Highway 42 and Kentucky 841 may be one motorists wish to avoid starting this Thursday and Friday afternoons.  "There will be a single blast on Thursday and again on Friday about 2 p.m. on both days," says Dan Hartlage, a spokesman for the East End Bridges Project.

Prior to the blast, for safety reasons, traffic in all directions will be stopped for between five to twenty minutes.  Starting next week, the blasts will become more frequent.  "On a typical day, throughout the construction process, when there is blasting underway, the blasts will occur two to four times per day," explains Hartlage.

The blasting will occur after the morning rush hour and before the evening rush to try to minimize traffic congestion.  The blasting will continue through the middle of 2015.

Hartlage says it is too soon to say how many days a week it will occur.  It is being done to build the 1,700 foot tunnel under U.S. 42 and the Drumanard Estate.

Hartlage outlines what nearby residents are likely to hear.  "They will hear a single blast," he says. "It will be the sound of a dull thud, they will hear it if they live in this immediate vicinity, it is not going to be a series of blasts; it is not going to be blasting all afternoon."

Some residents of the Bridge Pointe Subdivision have a direct view of the tunnel construction now underway with giant earth moving machines at work.  The residents WDRB spoke with say they are prepared for the noise and dust that come with the construction of the massive bridges project.

"If you don't know what is going to happen you might be a little concerned," says Bridge Pointe resident Joseph Quaye, "but it seems to me they know what they are doing.

Thursday of each week, the blast schedule for the following week will be posted on the bridges project's web site.
