Paving to start in November on torn-up segment of Centennial Boulevard
Started in early September, the $9 million project is in its first phase (between Garden of the Gods Road and Chesham Circle), with the initial focus on the two southbound lanes. This has meant temporarily realigning the northbound side between those streets to one lane each way.
Since September, the contractor, Kiewit Infrastructure Co., has scraped the old southbound pavement down to the dirt, added drainage improvements, regraded the roadway “crown,” removed the bulk of the old center medians (including the trees between High Tech Way and Chesham) and finished identifying and marking the utility lines below the right of way.
The crown is the curve designed across most roadways, so that drainage flows to the gutters on either side. The modern standard calls for a drop of 2 inches for every 100 feet, but the old Centennial crown had more of a slant, explained Joe Garcia, the project manager with city-contracted Wilson and Co.
As a result, in flattening the crown for the new Centennial, the center of the road will be about the same elevation as before, while on either side the curb/gutter/sidewalk will be
The crown correction has also required the removal of all the former curb, gutter and sidewalk. “Unfortunately, with concrete, you can't just lift it up and reuse it,” Garcia noted.
He said the next step in the project will be pouring the new concrete (including the new medians). This work is to start the week of Oct. 10. After that will come the paving, currently set to get going in the first week of November.
The city hope is to finish both sides before winter, but if weather makes that impossible (asphalt work is affected by cold), the project will be put on hold until spring. During that time, two lanes each way will be made available over temporary asphalt, city officials have said.
The overall project, between Garden of the Gods Road and Fillmore Street, is informally broken out into three phases. Plans call for Phase 2 (Chesham to Windmill Avenue - the middle section) and Phase 3 (Windmill to Fillmore - the southern section), to be fixed in 2017.
Plans call for the finished product to have two lanes each way, as before, plus a buffered bike lane on either side, contiguous sidewalks, and a connection to the Sinton Trail (which goes through a tunnel underneath Centennial, just north of Chesham).
The funding ($9 million, plus $3 million for design and preliminary stormwater work) is coming from the Pikes Peak Rural Transportation Authority (RTA), for which the project is an A-list item.
The last major work on the GoG-to-Chesham segment occurred more than 25 years ago, according to city officials.
