This multi-faceted project provided infrastructure solutions for an open space and Transit Oriented Development (TOD) at the Metro Center light rail station. We provided designs for a multimodal trail system to connect the RTD light rail station to the Highline Canal, including a pedestrian box culvert under Alameda (136-foot Conspan Arch pedestrian box culvert). The pedestrian element was added to meet the project goal of maximizing recreational potential and pedestrian amenities.


A shoefly roadway design raised east bound lanes of Alameda one foot, moved the lanes over to allow room for construction, and moved cars back after construction.


The project required two large water line relocations. In addition, we designed the lowering of 36” potable waterline, considered the various forces acting on the pipe and bends to design restraints and thrust blocks, and added a blow off and air vac. We designed the rerouting of an 8” waterline, adding various bends to the line. Finally, Calibre analyzed sewer lines for capacity, and the resulting alternative lowered two existing sanitary sewer mains and added manholes and drop manholes to the existing system.


Also required 2300 LF of 84” – 108” stormwater RCP.
