Construction on a busy Northwestside road could be delayed about a month.

Lafayette Road between 71st and 79th streets has been closed since March to replace an aging bridge over Eagle Creek.

Construction was originally scheduled to wrap up by the end of October but could be delayed until late November, said Kit Werbe, Department of Public Works spokeswoman. The Indiana Department of Transportation extended the completion deadline after the state delayed a notice to proceed on the project before it started.

“It is likely that the project will be completed prior to the contract completion date, probably around the end of this month; however, since most of the remaining work is weather and temperature dependent, the contractor won’t commit to an earlier date,” Werbe said.

Grading for the road was scheduled to start Thursday but delayed until next week because of the rain, Werbe said. The contractors also have paving work to complete.

“The only work remaining on the bridge itself is the railings,” Werbe said. “The contractor began forming those (Thursday), and they likely will be done by the end of next week.”

The Traders Point Collection Facility for household hazardous waste, 7550 N. Lafayette Road, will reopen when the road reopens.
