I have been saying spring is just around the corner. Here is a sure sign. In a few short months, we'll see orange barrels and road closures signs. Time to exercise the 'P' word, that stands for patience. Several road construction projects will be getting under way. From east to west, the I-69 road sign project is going to extend through Lapeer, Genesee, Shiawassee and Clinton counties. Nearly 100 miles of the expressway will get new signs. The price tag is $4.6 million.

Exclusive to Genesee County, there are other I-69 projects that are likely to close lanes and shift traffic. That list includes Irish Road Bridge repairs and six miles of resurfacing from M-13 to Elms Road.

Next, in less than two months crews will begin repairs on the Zilwaukee Bridge in Saginaw County. Michigan Department of Transportation, or MDOT, is reconstructing four miles of  I-75 and improving the Zilwaukee Bridge this year.

MDOT says it's important to make these improvements to maximize the life of the bridge and that stretch of I-75 in Saginaw County. In 2013, southbound lanes will get the makeover. Northbound lanes are targeted next year.Traffic will be shifted twice every week to ensure three open lanes during peak travel time. On Sundays, Mondays and Tuesdays, southbound lanes will be shifted to I-75 north.

Northbound traffic will be detoured to Northbound I-675. The rest of the week, Wednesday - Saturday, lanes are open on I-75 north. Southbound I-75 will be closed with traffic detoured to Southbound I-675.

Happy motoring.
