How predicted rain could impact road construction Original

SIOUX FALLS, S.D. (KELO) – Three major road construction projects are underway in the Sioux Falls area. In this Original, we look at the plans for these construction sites and the strategy to power through the wet weather ahead.

This Storm Center Update takes a look at the expected rainfall over the next few days.

The Highway 100 and Exit 402 project is valued at $55.6 million. The team is building a new bridge and reconstructing a single traffic signal at exit 402. The new Highway 100 will have three lanes in each direction, have a raised grass median and a two-foot wide splash guard adjacent to the back of the curb.

The I-229/26th St/Southeastern Ave project is valued at $37.3 million. The construction began on March 25th, 2019, and in October, the plans are to complete the bridges over I-229 and the Big Sioux River/BNSF. The South Dakota Department of Transportation and the City of Sioux Falls say the project will take two years to complete.

The Highway 115 project is valued at $18.3 million. The plans call for reconstructing 3.3 miles of Highway 115 (Minnesota Ave) just south of the 85th street intersection. The work the crew is doing involves grading, structure, concrete paving, curb and gutter, asphalt concrete pavement, storm sewer, traffic signals and lighting.

To learn how the construction crews plan to battle the weather ahead, check back later in the day on this Original.

Josh Peterson is one of the City of Sioux Falls’ engineers. He says when construction began for the South Eastern project the city and crew took into account the weather when they were sequencing.

“Rain always impacts construction, the benefit that we have in this construction is that we’re working up,” Josh Peterson said.

‘Working up’ meaning the project has built up some very high retaining walls. This will help when trying to work through the rain since the crew will be higher off the ground. Both teams also planned for this winter too.

“The contractor will be doing the snow removal in the work zone since they also maintain the traffic control,” Peterson said.

But even with the flooding from this year’s rain and snow, the project is on schedule. Peterson says all the ramps are open for I-229. However, starting this Monday, there will be night-time closures on the interstate while they set bridge beams.

“Overall, the project is going well and on schedule,” Peterson said.
