Martin Luther King (MLK) Extension
The Project team began construction activities on the MLK Extension in November. Scheduled work includes widening of roadways and bridges on Interstate 264 (I-264), replacement of the pedestrian bridge over I-264, extension of the MLK Freeway from London Blvd. to I-264 with an interchange at High St., and aesthetic treatments from Turnpike Rd. to London Blvd. This work will be performed through a series of lane closures along with temporary and permanent I-264 ramp closures.
View our MLK Construction Brochure for more information on planned construction activities impacting I-264.
MLK Extension Benefits
Extending the MLK Freeway from London Blvd. to I-264 with a partial interchange at High St. will:
Provide more direct access between the Midtown and Downtown tunnels.
Add a shorter, more direct route to the Downtown Tunnel from Portsmouth.
Allow motorists to easily choose between the Midtown or Downtown tunnels.
Better communicate traffic conditions via changeable message signs on the MLK Freeway.
Tolling on the MLK Extension
Tolling on the MLK Extension will begin once the extension is complete.
All vehicles that use the MLK Extension and one of the tunnels as part of a single trip will pay $0.50 to use the MLK Extension. All vehicles that use only the MLK Extension will pay $1.00.
A vehicle taking a local trip in Portsmouth entering or exiting the MLK Extension from the High St. or Portsmouth London Blvd. ramps will not pay a toll.
