As a first step in designing F Line stations, Metro Transit contracted with a firm to assist with field surveying. To complete this work, surveyors gather information about the existing space and utilities below the ground to create accurate measurements for designs and to avoid foreseeable problems before construction.
Field surveying has been completed for all F Line station areas south of 53rd Avenue, except for the southbound side of Central & 37th Avenue due to construction work in the area unrelated to the F Line. Field survey is currently underway on University Avenue north of 57th Avenue. Additional field work for drainage structure reports and locating the existing right-of-way is also ongoing.
Expect brief lane closures for geotechnical investigation beginning this month
Geotechnical borings are needed to sample soils before designing BRT stations. Borings are performed using a drilling machine with a hydraulic auger on the back of a truck. Crews will bore holes approximately one foot in diameter and 20 feet deep near each proposed station location. All holes will be re-filled the same day and seeded, in grassy areas, or patched with asphalt if they were originally paved. Noise from the work will be similar to a medium-sized diesel truck engine. We expect this work to start the week of December 4.
To perform the geotechnical investigation, the public can expect temporary lane and parking closures lasting for up to a day at planned station locations while borings are completed and holes are re-filled. Metro Transit is committed to minimizing the impact of this work and appreciates your understanding and patience.
