It’s a busy morning for Iowa transportation news. Here’s a look at what’s happening:

• The Iowa Department of Transportation has posted an interactive map that will help motorists avoid road construction delays beginning with this weekend’s Memorial Day travel. The state has 47 highway and bridge projects planned, many with detours or lane closures. The website gives the project location, description, start date, completion date and contracted cost for major projects. Not all state projects are listed. Motorists may also visit www.511ia.org for updates on road conditions.Read more
• The national nonprofit transportation research group TRIP reports that 22 percent of Iowa’s rural bridges were structurally deficient in 2014.

Iowa lawmakers raised the state fuel tax by 10 cents a gallon this year to raise approximately $200 million for projects. And the Greater Des Moines Partnership last week led a delegation of nearly 200 community leaders who pushed Congress to pass long-term funding for transportation projects. The current federal program expires on May 31.Read more
