The Eastern Extension of the President George Bush Turnpike (SH-190) starts in north Garland near Firewheel Town Center and will terminate at I-30. The last leg, which is being constructed by TxDOT, is across Lake Ray Hubbard and then a connection to I-30. Many support pylons and bridge spans have been constructed but much remains to be completed before the Fall, 2011, opening. Tugs and barges move equipment into place for the over-the-water project.

The Eastern Extension is a portion of the outer loop around Dallas and its suburbs that connects Interstate Highway (IH) 30 to the existing President George Bush Turnpike (PGBT). It is part of the Loop 9/State Highway 190 corridor first envisioned in the 1960s. Construction on the approximately 9.9-mile corridor began in October 2008. The project is expected to open to traffic in fourth quarter 2011.
 
Corridor Updates

• In Section 28, construction continued on the retaining walls. Crews
  continued to place main lane concrete pavement between SH 78
  and the Rowlett Creek bridge, and workers continued concrete
  bridge deck placements on both the east- and westbound Rowlett
  Creek bridges.
• In Section 29, the contractor continued to work on both sets of
  bridges: PGBT EE over Merritt Road as well as Miles Road over
  PGBT EE. In addition, sub-grade preparation for both main lane
  and frontage roads continued, as did the installation of intelligent
  transportation systems and roadway lighting. Placement
  of concrete pavement on main lanes is also scheduled to begin.
• In Section 30, the contractor continued assembling the DART
  railroad steel girder spans.
• In Section 31, construction continued on the retaining walls, paving
  of frontage roads and staged construction over Miller Road.
  In addition, moisture-treated sub-grade placement will continue
  for main lane pavement as will the construction of bridges over
  Miller Road.
• Section 32, which includes a bridge over Lake Ray Hubbard, is
  being constructed by TxDOT.

Next Steps

• Open the service road in front of the Mariners Cove subdivision in Rowlett, Section 30
• Finish DART bridge in Section 30 and open new DART tracks
• Continue construction on all sections

Sections 28 and 29, the two closest to north Garland, are showing the most progress. In several places the concrete roadway is already in place and preparations to pour more are obvious.
 
UPDATE: Proving that great minds think alike, Dallas Morning News reporter Ray Leszcynski today posts some additional information on the SH-190/I-30 interchange at the DMN Garland Blog. It may have less impact on north Garland residents than to others in the city, but it is very timely to the update and picture posted above.
