The project will widen the ramps from one to two lanes and the bridge overcrossing from two to six lanes, Including two turning lanes. This will help reduce congestion at freeway on- and off-ramps after a signal is installed at the intersection of Interstate 8 (1-8) and Dogwood Road this November. Options for the ramp design are still being considered.
The I-8/Dogwood Road area has experienced unprecedented rapid commercial and residential development, making this part of Imperial County the so-called commercial hub of the region. During busy commercial seasons, vehicle back-ups are experienced on the 1-8 ramps and main lanes. Traffic studies have determined that widening the ramps, in addition to signalizing and widening the bridge, is necessary to prevent congestion on 1-8 and Dogwood Road.
The estimated cost of the project is $33.1 million. Funding is coming from Congress ($1.7 million), developer contributions from the city of EI Centro ($4.5 million) and the Regional State Transportation Improvement Program ($26.9 million).
A Project Study Report was concluded by the city of EI Centro in June 2007. Construction is scheduled to begin in 2013, with completion in 2014.
