Interstate 80 through Dallas County has always had a notable sound as you drive on the concrete, although it’s not quite as distinctive as the freeway west of Adair.
But there’s been a different kind of sound there this year, that of vehicles hitting each other.
KCCI has a story about drivers who are not going slow enough in the construction area west of the Jordan Creek Parkway (not Drive) exit in West Des Moines. There’s some good drone footage showing the construction area from the sky. The conversion of the interstate to six lanes here has shrunk the width of the travel lanes and shifted them to the outsides using the shoulders while work goes on in the median.
Construction will go on until 2025. Like with I-380 between Cedar Rapids and Iowa City, it would’ve been better to have done it two decades ago, but expansion of the statewide four-lane network took priority.
