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.
