Rain delays new lane width restrictions on southbound I-380/eastbound U.S. 20 at the I-380/U.S. 218/U.S. 20 interchange in Black Hawk County #iatraffic

NEW HAMPTON, Iowa – June 20, 2014 – The past several days of rain has delayed the next phase of road construction work on southbound Interstate 380.  Width restrictions on the current single lane of traffic for southbound I-380/eastbound U.S. 20 on-ramp at exit 71 of the I-380/U.S. 218/U.S. 20 interchange near Evansdale will now begin at 12:01 a.m. Saturday, June  21, weather permitting, according to the Iowa Department of Transportation’s New Hampton construction office.

The road construction work will require narrowing the width of the current single open lane from 16 feet to 12 feet. The open lane will have concrete barriers on both sides of the lane. All loads over 12 feet wide will need to find another route. Advance signing will be in place to warn drivers of the width restriction. The current single lane for the westbound U.S. 20 on-ramp will remain at 16 feet wide.

Motorists should be alert for the possibility of slow or stopped traffic when approaching this area. To avoid congestion, the Iowa DOT advises drivers to consider alternate routes.
