The last vestige of Old Highway 10 in Coon Rapids will get a makeover this year.
The Coon Rapids City Council has approved plans and specification and ordered bids for bituminous street patching repairs.
This project will include mill and overlay work on the length of Coon Rapids Boulevard Extension, part of the original Highway 10 in Coon Rapids.
Coon Rapids Boulevard Extension starts just west of Culver’s on Coon Rapids Boulevard and enters Coon Rapids Boulevard again just before the Avocet Street intersection.
The two railroad bridges that cross Coon Rapids Boulevard Extension were built in 1917, according to City Engineer Doug Vierzba.
The street was built to a rural section over poor soils without concrete curb in most portions of the road, Vierzba said.
Coon Rapids Boulevard has a concrete surface under the bituminous surface which has prevented it from settling, despite the poor soil conditions, he said.
“It is not practical to rebuild the road with concrete curb and gutter,” Vierzba said.
Instead, a mill and overlay project will be done as part of the bituminous street patching repair work.
That will involve taking off two inches of bituminous and repaving the road with two inches of bituminous, Vierzba said.
Coon Rapids Boulevard Extension has not been resurfaced for 25 years and there is a lot of cracking, he said.
“The mill and overlay will create a smooth surface and it should be good for 10 to 15 years, although cracking will start to appear within a couple of years, Vierzba said.
Coon Rapids Boulevard Extension runs for seven-tenths of a mile.
The mill and overlay work has a cost estimate of $150,000 and will be paid for from the city’s state aid street account, for which the city receives state gas tax revenues.
The council will consider a contract for the project at its April 17 meeting.
The contract will also include patching for watermain breaks and for storm drain repairs, the cost of which will come from the water and storm drain utility funds, respectively.
Work is expected to begin in early-May depending on the contractor’s schedule.
