Diagram of a typical super street intersection (KY DOT)
Just yesterday, I mentioned that plans for a Loop 1604 super-street would be announced soon, and indeed the project was announced today at a buy prada iphone case Bexar County Commissioners Court meeting where the court approved kicking-in $900,000 of Advanced Transportation District funds to buy prada iphone case help pay for the $7.4 million project. The remaining $6.5 million will come from federal stimulus funds.
There will be three components to the project. The first, to start in May, will make improvements to the Braun/1604 intersection. I will get a buy prada iphone case copy of the plans from TxDOT as soon as I can buy prada iphone case and will pass-on the exact details of those improvements. However, it buy prada iphone case does not appear that the intersection will see the typical super-street design, that buy prada iphone case being replacing left-turns with turnarounds. Work on those improvements will take about a month.
Next January, work will begin on the buy prada iphone case actual super-street portion of the project, which will redesign the intersections of New Guilbeau, Shaenfield, and buy prada iphone case SH 151, replacing some left-turn movements with a combination of right-turns and buy prada iphone case turnarounds. Eliminating those left-turns allows for buy prada iphone case additional green time for 1604 through traffic. That project is expected to last seven months.
The final element of the improvements, which will begin late next year or in early 2012 in May 2011 and buy prada iphone case take a little over two years to complete, will build an buy prada iphone case underpass on SH 151 at Loop 1604, connecting 151 to buy prada iphone case Alamo Ranch Pkwy. That project will cost $18 million and will be funded separately.
It is estimated that the super-street will increase travel times on Loop 1604 by about 35% during the morning rush hour and 65% during the evening peak. The Alamo Regional Mobility Authority, which is currently conducting an environmental study for buy prada iphone case long-term improvements for Loop 1604, will design the project and obtain the buy prada iphone case required environmental clearances for it. TxDOT will then construct it.
