Construction crews have begun widening White Marsh Boulevard at Interstate 95 as part of the $1.03 billion express toll lanes project.
The roadway, also known as MD 43, will go from four lanes to six at the interchange, and two elevated ramps will be built to provide a direct link to the Interstate 95 express lanes. A new bridge will carry traffic over the interstate. The $142.6 million reconstruction is scheduled for completion in 2014.
The Maryland Transportation Authority estimates the work will generate 400 jobs.
When completed in two years, the I-95 express lanes will give motorists a choice between traveling for free between I-895 and White Marsh Boulevard or speeding their trip by taking toll lanes.
