Major traffic improvements coming to Maple Glen Triangle

The busy Maple Glen Triangle, the junction where Route 63 (Welsh Road), Norristown Road (SR 2052), and Route 152 (Limekiln Pike) meet, has long been a source of congestion and frustration for drivers traveling through Upper Dublin and Horsham Townships. 

With residential neighborhoods bordering the corridor and dozens of small and mid-sized businesses operating inside the Triangle, traffic has consistently outpaced the capacity of its three signalized intersections.

Officials have announced a comprehensive roadway improvement project designed to address safety concerns, ease congestion, and better manage traffic flow in the area, and that plan is already underway, according to officials. 

According to a report, Horsham Township has rolled out traffic signal changes at the intersection of Welsh Road and Norristown Road, aimed at improving safety and easing congestion at one of the area’s busier crossroads.

As part of the upgrades, protected left-turn signals have been added on Norristown Road in both directions for vehicles turning onto Welsh Road. In addition, a new right-turn-only lane has been created for drivers making right turns onto Welsh Road.

Township officials said the improvements are designed to reduce traffic conflicts and make the intersection safer for motorists.

The project is not yet complete. Final road line painting has been delayed due to recent inclement weather, though crews are expected to finish the work once conditions allow.

Planned Upgrades

Overall, there are many parts to the project up ahead. Those include:

• Modernized traffic signals with new equipment and updated timing at all three intersections.
• Road widening on Welsh Road, expanding to three lanes and adding turning lanes where needed.
• Widening of Norristown Road to include dedicated turn lanes and space for potential bike lanes in the future.
• Lane reconfiguration on Limekiln Pike to coordinate with Welsh and Norristown improvements.
• Centralized driveways to replace continuous curb cuts, improving both safety and circulation.
• Sidewalk construction and ADA accessibility upgrades.
• Enhanced drainage systems to reduce roadway flooding and improve long-term infrastructure durability.

Construction Timeline & Traffic Impact

Work is expected to begin in summer 2027, with substantial completion targeted for summer 2029. To minimize disruption, construction will be carried out in three stages:

Traffic will be shifted to keep one travel lane open in each direction while half of the roadway is rebuilt.

The process will repeat for the opposite side of the road.

Final work will require short-term traffic control measures to complete paving and finishing touches.

While delays are anticipated during construction, officials say the long-term benefits will significantly improve traffic safety and circulation throughout the Maple Glen Triangle.
