Sioux Falls Construction Chronicles I-90 & Cliff Avenue [PHOTOS]

One of the main construction projects for the city of Sioux Falls this season is a reconfiguring of the interchange at mile marker 399 on Interstate 90. This is the intersection of I-90 and North Cliff Avenue one of the main gateways to the city of Sioux Falls.

What follows is a close-up look at the current phase of construction and how travelers will navigate the construction zone.

The above picture is the newly fashioned westbound exit off the interstate. There are a couple of things to keep in mind to navigate this off-ramp.

First is a temporary crossover built for this project and the ramp speed limit of 25 miles per hour. Candidly, you could come off the ramp at a quicker pace than that safely, but remember this is a temporary structure and a lot of heavy vehicles will use this exit. The slower speed will allow the asphalt to last longer.

The angle for this exit is a bit different as well as you come off I-90, thus requiring the slower speed. Not to mention this is a construction zone, there are workers occasionally in this area.

Note the new off-ramp continues parallel to the old off ramp for this project with the accursed cones to guide you.

There is a traffic signal placed at the end of the new off-ramp to accommodate you.

As far as other considerations for travelers, there is currently two-way traffic on I-90 using the east bound lane. So getting on the super slab going east you will need to be wary of a tight fit. Getting on I-90 going west will be less stressful as head-to-head travel ends just after the interchange.

This look is heading south on Highway 115.  The entire project is to be completed by early November 2013.
