Project Background

120th Ave Excavation & Earthwork Oct 2105

October (2015) project activities on the 120th Avenue Connection included the continuation of utilities relocation (gas/electric/communications), continuation of excavation and earthwork (primarily west of the railroad near Colmans Way) and the completion of the project's scoped portion of the railroad shoo-fly to the existing railroad siding track area.

Work completed in November and December 2015 concentrated on the creation of a detour for the BNSF Railway at 120th Avenue (local), as well as the closure of Nickel Street between Commerce Street/Industrial Lane and U.S. 287 for the removal of the BNSF Railway siding tracks. This work allows crews to safely begin construction of the final phase of the 120th Avenue Connection/extension of SH 128.

A new railroad structure will be constructed and the tracks will be moved back to their current location when this phase of the project is completed approximately May 2018.
