City of Tyler: Grande Blvd. Extension

SPI developed route studies and schematics and prepared construction documents for this new location urban roadway in Tyler. The three phase project required a CLOMR from FEMA and related hydraulic studies, and an individual wetland permit from the USACE. Over $7 million of utility relocations were required. SPI was responsible for coordinating with the utility companies to get the utilities moved out of the new right of way. This 5-mile section of 4-lane roadway with raised median is in a densely developed area including residential and commercial development. SPI negotiated the acquisition of over 100 right-of-way parcels, drainage and slope easements.Twin 225’ span bridges (75-75-75) were designed over W. Mud Creek (Q100=13,500 cfs). The project includes over half a million cubic yards of roadway and channel excavation, of 155,000 SY concrete pavement, of 25,000 LF enclosed storm sewer and of 1,500 LF channel stabilization. SPI provided full-time construction representative services for all phases of this project which include material tracking, administration of pay applications and change orders, weekly construction meetings, and acting as a liaison to utility companies, property owners and TxDOT.

The first phase of the project was completed April 2006 at a cost of just over $6.3 million.Phase 2A opened for traffic in September 2009, and 2B opened to traffic in January 2010. The final construction cost for these two phases were $30 million. Total project cost for all phases, including right-of-way acquisition and utility relocation, was $50 Million.
