Paving under way on northbound side in Centennial reconstruction project
After several months of ground preparation, the contractor, Kiewit Infrastructure Co., began June 21 to pour, compact and level what will total 8 inches of fresh pavement in the northbound lanes between Garden of the Gods Road and Windmill Drive.
According to Ryan Phipps, Colorado Springs Transportation's project manager, the paving of that Centennial segment is scheduled to continue into early July, with motorists able to use it at some point after Independence Day.
The overall project - mainly regrading and resurfacing the four-lane arterial between GoG Road and Fillmore Street and redoing its curbs, gutters and sidewalks - is scheduled for completion by the end of October, Phipps said.
During the work, traffic is reduced to two lanes (one each way).
The GoG Road-Windmill northbound segment comprises what the city has dubbed Phases 2 and 4 of the five-phase Centennial project.
Completed in the fall of 2016 was Phase 1 (GoG Road-Chesham, southbound side).
Next to get attention will be Phase 3 (extending southbound Centennial from Chesham to Windmill) and Phase 5 (northbound and southbound Centennial from Windmill to Fillmore). That work is slated for completion in September, Phipps said.
He added that he is “very pleased with the progress that Kiewit is making. They are on schedule to complete the project within the original amount of contract time.”
One unforeseen problem was utilities that had been installed years ago at too shallow a depth. “This proved to be very difficult to work through, but we have worked through each of these issues one by one,” Phipps said. “We have also dealt with very poor soil conditions in the Holland Park neighborhood vicinity but have overcome them through the use of geogrid stabilization.”
Geogrid is a term for a type of structural material that can be installed under roadway pavement to mitigate against ground shifts below it.
“Kiewit, CSU [Colorado Springs Utilities], Century Link, Comcast and city personnel have met weekly for nearly a year now to ensure that the project can progress effectively and efficiently,” Phipps summarized. “I think that work is starting to be evident as this project is nearing completion.”
Project funding is coming from the Pikes Peak Rural Transportation Authority (PPRTA). The Centennial reconstruction is on the PPRTA's A-list for voter-approved projects. The job is not part of the Fillmore-to-Fontanero Centennial extension project to the south, which is also on the A list and tentatively slated to start this fall.
