Lengthy On-Ramp Closure Coming to I-229 in Sioux Falls

One of the several construction projects on Interstate 229 in Sioux Falls is about to impact access to the roadway.

Beginning Monday (May 20), the South Dakota Department of Transportation is shutting down the southbound on-ramp at Benson Road. The work is part of the Diverging Diamond Interchange (DDI) construction project.

The closure will allow crews to install, grading, and concrete surfacing.

The ramp is expected to reopen Monday, July 1.

During the month-long closure, I-229 on-ramp traffic will be detoured to Rice Street via Benson Road and Rice Street.

The DDI project will reconstruct approximately one and one-half mile of Benson Road and a mile of I-229 ramps. Work includes construction of a DDI, constructing a structure, grading, concrete surfacing, curb and gutter, storm sewer, lighting, signals, permanent signing, and pavement marking.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
