183A Turnpike Project – Phase II Page 3 of 13
Quarterly Construction Progress Report, No. 6
Construction of 183A Phase II is 75% complete. The team is currently on schedule to open the
five mile tolled expressway in the spring of 2012.
Progress for the period is highlighted by continued mainlane roadway paving throughout the
project as well as bridge construction at Scottsdale Drive. It is anticipated that the new bridges
over Scottsdale Drive will be open to the traveling public in late October 2011. This period also
marked the start of concrete bridge railing placement.
Other activities include toll gantry foundation work, sign column construction, and construction
of drainage facilities across the project area. Block wall placement and preparation for rock
lining is occurring in the project's multiple water quality ponds. Construction also continues on
the pedestrian bridges for the Shared Use Path component of the 183A Phase II construction.
The following tasks continue from the last reporting period: concrete production at the
Contractor’s temporary concrete batch plant facility; coordination with Telvent, the project's
toll integrator contractor; soil nail wall construction at Scottsdale Drive; MSE wall placement
throughout the project area; ongoing traffic control activities; and erosion control.
The Mobility Authority's GEC continues to perform construction inspection and oversight of the
Contractor, including all materials testing. Offsite material fabrication plant inspections
continue to take place.
