Lane restrictions could impact nighttime travel on Route 30 and Route 100 this week.

The Pennsylvania Department of Transportation is working on a 14-month project to install and replace raised pavement markers on several state highways in the Greater Philadelphia region continues next week in Philadelphia and Chester County.

Here’s the schedule, weather permitting, of the work next week from PennDOT:

• Lane restrictions will occur on northbound and southbound Route 100 (Pottstown Pike) between Route 30 and Swedesford Road in West Whiteland Township on Sunday (Oct. 7) through Tuesday (Oct. 9) from 10 p.m. to 5 a.m.;
• Lane restrictions will occur on the ramps at the interchange of Route 100 (Pottstown Pike) at Route 30 in West Whiteland Township on Sunday (Oct. 7) to Tuesday (Oct. 9) from 10 p.m. to 5 a.m.;
• Lane restrictions will occur on northbound and southbound Route 100 (Pottstown Pike) between Ticonderoga Boulevard and Route 401 in Upper Uwchlan and West Vincent twps. on Wednesday (Oct. 10) through Friday (Oct. 12) from 9 a.m. to 3 p.m.

Crews will install and replace reflective markers along center lines, edge lines and ramps to improve visibility and safety for drivers at night and in bad weather such as rain, fog and snow.

During installation, crews will occupy one lane to conduct a slow-moving operation. Motorists are advised to be alert of this moving operation and to expect possible slowdowns when driving near work crews.

D.W. Miller, Inc. of Huntingdon, Pa. is the contractor on the $304,310 project, which is financed with 100 percent federal funds. The project is scheduled to be completed by October 2013.
