    COMMERCE CITY — One weekend done but plenty more to go as the Colorado Department of Transportation resurfaces and repairs Interstate 270.
    The roller coaster of bumps along the eastbound stretch of I-270 between mile markers 3 and 5 has been resurfaced after a weekend-long closure of the interstate. It’s the latest work done in a $4.1-million project handled by Martin Marietta Materials, which is slated for completion in June.
    All lanes of eastbound I-270 were closed between Interstate 76 and Interstate 70 for the work. According to a CDOT news release, other work included paving and repairs to shoulders and grade improvements, all with the intention of improving overall road quality and safety before winter weather arrives along the Front Range.
    Motorists looking to make the trek from the northern Denver metro area to Commerce City were detoured from I-76 and US 36 to southbound I-25 and eastbound I-70.
    A similar Friday-to-Monday closure of the westbound lanes of I-270 between I-70 and I-76 is slated for the weekend of Oct. 5, weather permitting.
    “Last year, we repaired multiple bridge decks along eastbound and westbound I-270 to improve the roadway surface,” said CDOT Resident Engineer Neil Lacey. “The current project expands upon the recent improvements, by paving about one mile of I-270, repairing shoulders and eliminating the roller coaster effect that motorists experience when traveling I-270. The reason for the weekend closures is to make the initial improvements to the roadway, which will and help reduce potholes often formed during the spring and winter. We will then complete the remainder of the project next spring.”
    Once complete, the project will have seen the following improvements:
• Rotomilling and pavement of three miles of I-270 between just south of Dahlia (56th Avenue) and I-76.
    • Correction of the profile of the roadway between the South Platte River and State Highway 265 to eliminate small hills and the “roller coaster” effect for motorists.
    • Rotomilling and pavement of several bridge decks on I-270 and minor repairs to the bridge over Vasquez Boulevard.
    • Repairs to the badly potholed shoulders and resurfacing of the shoulders south of Dahlia Street.
    • Removal and replacement of damaged guardrail along I-270 and the ramps.
    • Installation of ramp meters at the ramp from westbound Vasquez Boulevard to westbound I-270 to help regulate the flow of traffic during peak hours.
