Pflugerville officials expect the current phase of construction on Kelly Lane to be completed on schedule in December, despite some engineering hitches and unexpected delays, officials said Wednesday at a city council meeting.

The portion of Kelly Lane between Falcon Pointe Boulevard West and Murchison Ridge Trail is currently slimmed to a narrow, two-lane road bordered by orange barrels and barricades.

The goal is to widen the road and include turning lanes, sidewalks, medians and new traffic signals. That should relieve traffic to area homes, schools, business and the yet-to-be-opened Hawaiian Falls water park at SH 130 and FM 685. Raised curbs and stormwater drains will also be installed.

Construction has uncovered infrastructure the builders and city officials did not know existed, some of it so old it did not appear on any plans, Pflugerville City Engineer Dan Franz said.

For instance, Franz said, builders hit a wastewater main that was not noted in plans, "and it was live."

"There isn't a construction project out there that doesn't have issues and hiccups and things we uncover. This project has been no different," Franz said, adding that the project was on schedule.

Franz said relocating wires along Kelly Lane slowed the project between December 2013 and February. Nevertheless, the project's contractor Cash Construction has made up for the lost time.

The project initially began in September 2011, with the roadside cable relocation. The contract for roadwork was issued in November 2013, and roadwork construction began a month later.

Construction is currently on the southern side of Kelly Lane. Work will shift to the northern lanes once some cabling is relocated and work on a traffic signal is completed.

All water lines along the road have been installed, Franz said, and testing on the pipes should be finished by May.

The city of Pflugerville website has more information detailing the ongoing construction.

Pflugerville Mayor Jeff Coleman said area residents have responded well to the project.

"Our citizens are doing what we asked them to do, they are finding other ways around," Coleman said. "Opening up Colorado Sand [Drive] and getting Pflugerville Parkway in better shape before we did this was a stroke of brilliance."
