Update on I-69 Extension in Indiana

<< < (3/813) > >>

It's a big chunk under construction because 1) Indiana's share is coming out of the toll road lease yeild and 2) the governor and INDOT took advantage of the recession and lower than expected bids. The schedule was accelerated to avoid any increase in costs.

From the Evansville Courier-Press: "UPDATE: Portion of I-69 project receives final approval on environmental impact "

http://www.courierpress.com/news/2011/jul/25/portion-i-69-project-receives-final-approval-envir/

"The Indiana Department of Transportation announced Monday the state has completed its set of plans for a section that will run from the Crane Naval Surface Warfare Center to Bloomington.

It expects to win approval from the Federal Highway Administration later this summer, and at that point, construction can begin."

Those outside breakdown lanes are what, two feet wide? What's the deal with that???

The shoulders you're seeing are the asphalt underlayment for the final concrete surface.  The shoulders, when completed, will be concrete of standard widths (10' on the right and I think 4' on the left, or maybe it's 5').  At the bottom of the photo it looks like the contractor finished the shoulders on a short portion just wide enough for construction vehicles and machinery to cross both carriageways without damaging the edges of the travel lanes.  Finishing off the shoulders the rest of the way is probably one of the final construction steps in this project, followed by rumble strip grinding, diamond grinding the travel lanes, and finally striping.

I should also add that I commend InDOT for building this highway correctly the first time with concrete!  Having recently moved from a state that primarily uses asphalt (Tennessee) to one that recently built several new roads in concrete (South Carolina), it's good to see other states spend the extra money for a surface that I feel provides more advantages than disadvantages, both from a longevity and a safety standpoint.

I would say those are the final shoulders. Below is a photo from the recently-opened US 24 east of Fort Wayne. It has PCCP, but with asphalt shoulders. The new US 31 freeway has the same thing, but the high volume freeways generally get PCCP for everything.

Looks like Pete Rahn's "Pratical Design" has made it to the Hoosier State.
