New Blue Route traffic pattern to start Monday

If you get on the Schuylkill Expressway from the southbound Blue Route, you really should read this.

If you get on the Schuylkill Expressway from the southbound Blue Route, you really should read this.

Starting Monday, weather permitting, motorists will see a new traffic pattern on a 4-mile stretch of the Blue Route (I-476) in Montgomery County that is being rebuilt.

PennDot says it will extend a southbound express lane from the Pennsylvania Turnpike Mid-County Interchange to just south of the Interstate 76 (Schuylkill Expressway) Interchange

The express lane will be established on the northbound side of the highway, leaving two local lanes on the southbound side.

This means southbound motorists wishing to exit at I-76 will have to stay in the local lanes.

Drivers will not be able to access the I-76 off-ramps and the ramp to Route 23 from the temporary southbound express lane.

Speeds also will be reduced to 45 m.p.h. through the work zone.

PennDot will keep three lanes of traffic open in each direction on I-476 during peak travel times for the duration of the project. Once barriers are in place, occasional weeknight lane closures may occur from 10 p.m. to 5 a.m., with short-term, 15-minute traffic stoppages possible from 1 a.m. to 5 a.m.

PennDot plans to stop using temporary express lanes on I-476 on Oct. 31, 2011.
