Sukut Construction Inc. Begins Construction of Alton Parkway Expansion

Share Article

Sukut Construction, experts in road and highway construction, will complete the final section of Alton Parkway connecting it to the Orange County Toll Road. This will take as many as 37,000 cars off local roads by 2025.

Sukut Construction has begun mobilizing for the $25.5 million construction of the final two segments of Alton Parkway. This traffic circulation project has been in the making for 30 years.

Sukut won an $18.5 million contract in July 2009 from Orange County and a $7 million contract from the City of Lake Forest in September 2010 to construct the last portions of the parkway within each of their jurisdictions. Both projects are being constructed simultaneously and together will link Interstate 5 to the 241 Toll Road.

“The county and the city have both been working on this project since 1981,” said Sukut CEO, Michael Crawford. “It will be a huge traffic relief when it opens.”

The completed route is expected to take as many as 37,000 cars off local roads by 2025.

Sukut’s contracts call for construction of four lanes of divided highway and grading to accommodate a future expansion to six lanes. A one-mile section of Alton Parkway within city limits will run from Towne Centre Drive to Commercentre Drive, and is expected to be completed in June 2011. At this point, the county takes over to extend construction another 1.1 miles to Irvine Boulevard. The expected completion date for this final portion of the work is set for October 2011.

The county contract includes construction of a substantial double reinforced box culvert beneath the roadbed to divert from an existing wash that floods in the winter. The culvert will be 2,000 linear feet, 20-feet wide and 20-feet high.

Sukut Construction is California’s largest mass excavation and grading contractor, previously moving 150 million cubic yards of earth a year. It is ranked within the top 400 largest contractors in the nation. Its projects range from highway construction to residential grading to wastewater management systems. Current projects include the construction of four, 60-acre wastewater treatment ponds holding more than 1 billion gallons for the Los Angeles Sanitation District; the Chiquita Canyon Reservoir in Rancho Santa Margarita, designed to provide enough emergency water to supply 168,000 families with 200 gallons of water per day for one week; and the construction of a section of the 905 Freeway in San Diego County. The company recently completed grading for a section of the U.S.-Mexico border fence.

Sukut, in its 41st year, is headquartered in Santa Ana, California, with offices in Oceanside, Los Angeles, and Riverside, California. For further information call 888 785-8801 or
