    Years of water, power and road work on and under Colesville Road are expected to culminate this year, as several overlapping projects begin to wrap up.
    A WSSC water main replacement project will enter its final phase later this spring. The utility company has spent the last two years replacing nearly two miles of transmission and distribution lines under Colesville Road between Georgia Avenue and the Beltway.
    The "big dig" for the water main work and concurrent Pepco upgrades was slowed following the discovery of hard bedrock underneath Colesville Road.

    "When we go to lay in a transmission line we have to dig a little deeper. We anticipated that, but what really delayed this project was when we realized we had granite. That takes longer to drill through," said WSSC spokesperson Jerry Irvine.
    Irvine said the utility company is well-coordinated with Pepco and the Maryland Department of Transportation. The final phase of work in downtown Silver Spring is set to begin later this spring.
    The MDOT State Highway Administration has announced a mile-long stretch of Colesville Road (Route 29) will be paved between Georgia Avenue and Sligo Creek Parkway. This work will likely be completed following the digging associated with the water line and power upgrades.
    In addition to the customary milling, paving and restriping, the curb and gutter system will be revamped in places. Several concrete bus pads will also be improved.
    The roadwork will occur on weekday middays through 3 p.m. and during overnight periods. Utility crews are permitted to block up to two lanes as late as 3:30 p.m. on weekdays. While the utility work will be winding down near the Beltway, work zones closer to downtown Silver Spring will be necessary through the end of the year.
    The Route 29 Bus Rapid Transit system is scheduled for launch in early 2020. The system will include stops at Georgia Avenue, Fenton Street and University Boulevard near Four Corners. The implementation of traffic signal priority to extend the green light or shorten the red light duration for BRT vehicles is ongoing.
