widening

The Veterans Expressway FL589, a major highway  going north from the west of Tampa is having a 7 mile, 11km stretch widened from mostly 2x2 lanes up to 2x4 lanes and getting all-electronic toll (AET) collection.  It is a $236m project - estimated  construction cost $202m, design $20m, right of way $14m.

Colorado DOT and a so called High Performance Transportation Enterprise of the state are seeking private sector proposals for improving travel in the I-70 Mountain Corridor west of Denver toward Silverthorne, Vail and Eagle.  They are looking for competitive proposals to an unsolicited proposal from transit specialist Parsons.

Widening into a median can be a very economical method of adding to capacity. Example is 36 lane-km, 22.4 lane-miles being added to the 407ETR in Toronto Canada. This adds two lanes each direction for 9km, 5.6 miles between H404 to Markham Rd.  (see map)

A joint venture of Aecom, Greenman-Pedersen (GPI) and Parsons Brinckerhoff will be paid $164m for construction management services on the New Jersey Turnpike $2.5b widening project getting under way. The contract has just been signed. The three engineering firms will be responsible for supporting the Turnpike Authority during the construction.

November 22 and 23 Orlando Orange County Expressway Authority (OOCEA) opened 1.4km (0.86 miles) of two extra lanes eastbound on the FL408 East-West Expressway over the Lake Underhill Bridge between Conway Rd to Crystal Lake Drive. This links two recently widened segments either side eliminating a "pinch point".

Transportation Corridors Agencies who run The Toll Roads in Orange County California celebrated the opening of a third lane each direction at the 241 or Foothill/Eastern Toll Road this week. For about 6km (4 miles) each direction third lanes have been added in the median of the far northern end of the 241 right up to the connector ramps of the interchange with the CA91 freeway.

Maine Turnpike Authority's ten year plan forecasts much slower growth in traffic, and as a result a widening project through the western edge of the Portland area is being deferred at least five years. Traffic on the Maine Turnpike grew steadily from around 100k/day in 1990 to an average 170k/day in 2004 and remained at about that level through 2007.

A lot of the campaigning for the next governor in New Jersey is about who will get the most windmills erected and taxes contained and jobs saved, but incumbent Gov Jon Corzine is making a major pitch for enhancing tollroad capacity, showing up at two big groundbreakings in recent days, playing for the cameras.

July 2 Corzine and leading officials were at Hightstown for ceremonies to celebrate a start on widening the NJ Turnpike Exits 6 to 9.

Pennsylvania Turnpike Commission has finished a total reconstruction and third laning on the westernmost 15km (10 miles) of the east-west mainline.

Pennsylvania Turnpike Commission have suspended further work on a 10km (6 mile) rebuild project and a new all electronic toll (AET) interchange on the northwest fringe of the Philadelphia area because of inability to gain acceptance of normal stormwater basins. They said in a March 24 letter that local demands for expensive poured concrete stormwater storage or dispersion technologies rather than regular stormwater dams make the project unaffordable.
