Bloomington Lindau Lane Grade Separation

Bloomington, Minnesota

In 2012, the SRF team was awarded the multi-million dollar final design of the Lindau Lane Grade Separation – the lead agency is the City of Bloomington. As part of their plans for the South Loop District, the City is initiating two transportation components to support their vision: the TH 77 to Lindau Lane Ramp Safety Improvement and the Lindau Lane Grade Separation between the TH 77 Ramps and 24th Avenue. This project includes the roadway, structural, utility, and urban design elements, which was constructed in two seasons. The project on Lindau Lane separates pedestrian and vehicular access to the Mall of America from the through traffic on the roadway.

Key project issues that the team addressed include:

  • Management of traffic in the heavily traveled area, including developing work zone traffic control and construction staging plans. Strategies include work zone traffic control plans and intelligent work zone devices, temporary regional and local wayfinding dynamic and static signs, temporary traffic signal design and timing plans, and pedestrian access and circulation signing and guidance
  • Design of a bridge and plaza capable of supporting a pedestrian and vehicle plaza and future expansion of the Mall of America over the roadway
  • Comprehensive landscape/streetscape plan for the corridor and plaza
  • Extensive coordination with private utilities
  • Design and implementation of complicated hydraulic storm sewer systems
  • Operations evaluations  along Lindau Lane to assist in developing roadway and intersection design
  • Watermain and sanitary sewer replacement
  • Traffic signal design and timing
  • Right of way and easement requirement identification

AutoCAD Civil 3D was used to prepare construction plans for the roadway reconstruction, retaining walls, tunnel, storm sewer, and utilities. The design team identified ways to expedite construction and minimize impacts to local roadways, parking lots, and mall operations.

The SRF team delivered a design that was bid significantly below the budgeted cost. We also assisted the City with construction activities and management during the 2013 and 2014 construction seasons.
