Philadelphia-based Hill International says PennDot has given it a $21.7 million contract to provide construction-management services on nine sections of Interstate 95 in Philadelphia over the next 10 years.
The state plans to rebuild and widen the highway, frequently subject to jams that delay truck and commuter traffic through the city, for example during rush hour in Northeast Philadelphia.
Hill says the work also will include replacing the "dynamic message signs" that warn of traffic back-ups with permanent installations, and upgrading PennDot's Regional Transportation Center.
A publicly traded company that works on projects in many countries in Europe, Asia, North Africa, and the Americas, Hill says it has worked on PennDot projects worth $1.7 billion on I-95 alone since 2000.
"We are proud to be continuing our role," Hill senior vice president and mid-Atlantic manager Michael V. Griffin said in a statement.
