Engineering firm unveils I-70 improvement project

International engineering firm Parsons Corp has unveiled its proposed US$3.5 billion project to ease traffic on Interstate 70 through the central mountains in Eagle County, Colorado. Parsons had submitted an unsolicited proposal to Colorado Department of Transportation in 2011. The three-phase project would include tolled express lanes and a bus rapid transit system and be completed as soon as 2021.

International engineering firm 4089 Parsons Corp has unveiled its proposed US$3.5 billion project to ease traffic on Interstate 70 through the central mountains in Eagle County, Colorado.  Parsons had submitted an unsolicited proposal to 5701 Colorado Department of Transportation in 2011.
 
The three-phase project would include tolled express lanes and a bus rapid transit system and be completed as soon as 2021.
 
The express lanes would be reversible to accommodate peak traffic flows to and from the mountains. The project would also straighten some curves on the interstate and resurface the existing lanes.
 
Tunnel bores would have to be added at places such as the Eisenhower Tunnel, and parts of the new lanes would be suspended like the current highway is through Glenwood Canyon.
 
"This is a very, very aggressive schedule," said Jim Bemelen, Parsons' mountain corridor manager. "It's unlikely, but the project could be completed by 2021."
 
"We are very concerned about minimising the footprint as much as possible," said Ralph Trapani, Parsons program director.

    An impending move to free-flow charging prompted a search for automated dangerous goods identification and over-height detection systems at the Thames Crossing to the east of London. Manned toll booths are increasingly being consigned to history by the onslaught of all-electronic charging. However, a secondary function of the traditional manned plazas has been to prevent non-compliant vehicles using the facility or to tell a driver that that they need to use a specific lane or wait for an escort.

  • European tunnel upgrades following new safety legislation

    Across Europe there is a very mixed picture of compliance to latest safety standards for road tunnels. Best practice has emerged, however, in the wake of European legislation. Jon Masters reports High profile fatal fires following accidents in the Mont Blanc, Tauern and Gotthard tunnels prompted the 2004 European Union Directive 2004/54 on road tunnel safety. This meant all EU member states would have to meet new standards of safety in road tunnels by 30 April 2014. The Directive applied to all tunnels over
