NORMAN — Motorists on Interstate 35 may notice some ongoing construction as they pass through Norman.
Crews contracted by the state Transportation Department are building a sound barrier along I-35 near the Lindsey Street/State Highway 9 interchanges. The barrier will serve as a buffer for houses that back up to I-35.
I-35 will be widened from four to six lanes from Main to the Canadian River bridge, and auxiliary lanes will be added for the on-off ramps between Main and Lindsey.
The interchanges at Main, Lindsey and SH 9 East will be reconfigured, and improvements will be made to the Canadian River bridge as part of the project.
The work will be done over the next eight years as money becomes available, state transportation officials said.
State-contracted crews also are working on new exit and entrance ramps on the northeast corner of I-35 and Robinson Street as that interchange undergoes improvements. That work should be completed this year.
