Katy Freeway expansion gets the green light
Reconstruction and expansion of the Katy Freeway (I-10) at Houston at a total cost of $1.1 billion began in June.
Gary Trietsch, TxDOT Houston district engineer, said the groundbreaking was held on a Saturday and work began the next day. Work on that seven-mile portion from Mason Road to Park Ten will go 24/7 for the next 35 months.
Bids were opened July 1 on two other projects three miles from Katy to Grand Parkway, the I-10/I-610 interchange, and 2.6 miles of I-610 south to Post Oak Boulevard. Trietsch expected work on both would start in October.
Before the project is over in 2009, said Trietsch, TxDOT will reconstruct 23 miles of interstate freeway, while under traffic, and reconstruct two freeway-freeway interchanges and 27 grade-separated intersections. The existing highway has 11 lanes; the reconstructed highway will have 18 to 20 lanes, including four-lane mainlanes in each direction, three-lane frontage roads and one or two managed lanes. Most notable are the four toll lanes in the middle.
Parsons Brinckerhoff Quade and Douglas, Inc. is the general engineering consultant, with nine subconsultants. There are 10 section design consultants, 30 subconsultants, and seven construction contractors.
The story of how tolls were added to I-10 and the financial involvement of a local partner is the forerunner of how expensive major facilities likely will be built in the 21st century.
John Mack, FHWA district engineer for South and East Texas, said that the federal Value Pricing Program enacted in 1991 allowed Texas to permit fewer than two persons in its High Occupancy Vehicle (HOV) lanes on the Katy.
Trietsch said drivers without passengers can use the HOV lanes if they buy toll tags that record the vehicle identity when it uses the lanes. The concept has not been heavily used in the first several years about 200 a day, said Trietsch.
TEA 21 okayed tolls on existing interstates on a pilot basis.
The Harris County Toll Road Authority (HCTRA) came up with an offer of $250 million to jump start the project, to be repaid from tolls on the four middle lanes, all collected electronically. HCTRA agreed to go with value pricing and the funding agreement between TxDOT, FHWA and HCTRA was signed March 14.
A local group, Katy Corridor Coalition, filed a lawsuit last September opposing the design. It asserted the need for more detailed studies, wanted sections of the mainlanes to be depressed, and expressed concern about preserving right of way for future transit alternatives.
