A preliminary design agreement for eventual work on Glade Road was approved by the Colleyville City Council.

The $793,639 contract with Transystems Corp. is to study the road and prepare a preliminary design for the segment from half-mile east of Precinct Line Road to Heritage Avenue. The preliminary design also will cover improvements at Glade Road and Bluebonnet Drive and Glade Road and Riverwalk Drive.

Transystems will look at alignments and rights of way, do survey work, study drainage and set up public meetings.

Extensive public involvement is expected to include a dedicated website, according to background material provided to the council.

Several public meetings are expected, as well as some 12 meetings with stakeholders involved.

Regular e-updates and social media updates also are included, as are alternate route maps and signs.

Once a preliminary design is completed, it will come to the council, which can make revisions if necessary.

The preliminary phase is expected to take a year. Construction could begin in late 2014 or early 2015.

The council on Feb. 19 authorized the staff to conduct contract negotiations and finalize the agreement.

The money will come from the city's perimeter street fee account and the tax increment financing district.
