Construction June through December 1998

The I-25, Meadows/Founders Parkway Interchange Project began in June 1998. Phase 1 was completed in December and included construction of the south half of the new bridge, storm sewer, utility work, underground wiring for lighting and traffic signals, concrete pavement, and ramp construction. The majority of the embankment was placed and some of the old ramps were removed. The old bridge was removed during December allowing work to begin on Phase 2.

Work on Phase 2 of the interchange reconstruction at the intersection of I-25 and Meadows/Founders continued through the winter as weather allowed. Phase 2 work included the north half of the new bridge, reconstruction of the pavement on Meadows and Founders Parkways, and completion of the new traffic signals and lighting.

Construction January through May 1999

In February the work focused on construction of the north half of the bridge foundation. This included the block abutment walls on the north side of the new bridge, concrete footings atop the walls, and pier work in the median of I-25.

Phase 1 construction of the bridge with the temporary wire basket support system.

Phase 2 construction adjacent to Phase 1 of the abutment wall.

Construction workers place reinforcing steel in the pier cap. The pier cap, which sits atop the pier columns, supports the girders and the deck.

The work continued on guardrails, retaining walls, and final drainage items. The sound walls were completed in April. At the end of February, traffic lanes were moved along Meadows/Founders to allow the contractor to prepare the roadway for new concrete pavement. During the months of March, April, and into May, the concrete paving contractor replaced the pavement for westbound traffic along Meadows and Founders Parkways. The approaches to the north half of the bridge, curb, gutter, and sidewalks were completed as well. The electrical contractor completed work on the lighting and new traffic signals allowing the new southbound off-ramp to be opened to traffic. Crews prepared to place the concrete deck on Phase 2 of the bridge. On Friday, March 28, ironworkers began installing the reinforcing steel (see photo). In the foreground, reinforcing steel is extruding from the pre-cast concrete girders and Phase 1 of the deck. In the background, ironworkers are placing the reinforcing steel in the deck. The deck and girder steel was later tied together to form one large mass. Construction June through August 1999 Sema's pipe crew extend culverts in the northwest quadrant near I-25. The guard rail was removed after the area had been regraded. A worker sprays curing compound on the newly poured concrete deck the night of April 26. A crew places asphalt paving on the new loop ramp from westbound Meadows to southbound I-25. This ramp was opened at the end of June and traffic began using the north half of the new bridge. Equipment in the background is re-grading the area where the old southbound off-ramp was. The new southbound off-ramp was opened and the old ramp totally removed. Crews re-graded the areas between the ramps and I-25 and covered them with topsoil and native grass seed. (See photo) The north half of the bridge was opened and the interchange was made fully operational. Work crews finalized the remaining finish work items including sidewalks and medians, sign installations, striping, slope paving, and concrete painting in July and early August.
