Islamabad T-Chowk Flyover and Shaheen Chowk Underpass Start in Sept 2025 — Costs, Bids, Maps

Islamabad T-Chowk Flyover and Shaheen Chowk Underpass are two major infrastructure projects recently approved by the Capital Development Authority (CDA) following a meeting with Interior Minister Mohsin Naqvi. Set to begin in the first week of September 2025, these projects aim to enhance city connectivity, streamline traffic flow, and provide commuters with faster, safer travel across Islamabad. The initiatives come with substantial investments of Rs. 1.4 billion and Rs. 1.3 billion respectively, reflecting their importance in modernizing the capital’s road network.

The Capital Development Authority (CDA) recently gave the green light for two key infrastructure projects during a board meeting, emphasizing the need to modernize Islamabad’s road network. Interior Minister Mohsin Naqvi played a pivotal role in facilitating discussions and ensuring swift approvals. Islamabad T-Chowk Flyover & Shaheen Chowk Underpass projects—deemed urgent due to rising traffic congestion and the need for improved city connectivity—are expected to break ground in early September 2025, marking the start of a transformative phase for the capital’s transport infrastructure.

T-Chowk Flyover Project

The T-Chowk Flyover is set to become a key solution for easing traffic at one of Islamabad’s busiest intersections. By providing a dedicated multi-lane overpass, the project aims to reduce congestion, improve commuter safety, and ensure smoother flow for vehicles traveling between GT Road and Islamabad Expressway. The flyover’s design also incorporates a detailed traffic redirection plan to minimize disruptions during construction. Key details of the project include:

• Cost & Length: Estimated at Rs. 1.4 billion, the flyover will stretch approximately 570 meters.
• Location: Strategically positioned at the intersection of GT Road and Islamabad Expressway, a critical entry and exit point for the city.
• Purpose: Designed to alleviate traffic congestion and streamline vehicle movement at one of Islamabad’s busiest junctions.
• Design & Features: A modern multi-lane flyover featuring a comprehensive traffic redirection plan to minimize disruptions during construction.
• Reported Contractor/Bids: The lowest bid has been submitted by HCS + ZKB, with final confirmation pending from CDA authorities.

Shaheen Chowk Underpass Project

The Shaheen Chowk Underpass is being developed to improve traffic flow at a vital junction connecting Ninth Avenue and Khayaban-e-Iqbal near Margalla Road. By diverting Khayaban-e-Iqbal traffic underground, the project aims to reduce surface congestion and provide a safer, faster route for university students, government employees, and daily commuters. The design also ensures smooth connectivity between Ninth Avenue and the adjacent service road. Key details of the project include:

• Cost: Estimated at Rs. 1.3 billion.
• Location: Junction of Ninth Avenue and Khayaban-e-Iqbal, near Margalla Road.
• Design: Khayaban-e-Iqbal traffic will pass underground, while the top slab links Ninth Avenue to the service road.
• Purpose: Facilitate movement for university students, government employees, and daily commuters, easing congestion at this busy junction.
• Bidding Status: Three contractors have submitted bids, with the lowest bidder yet to be officially confirmed.

3. Completion & Finishing: Installation of road surfaces, barriers, signage, and final safety inspections.

Key Milestones to Watch:

• Completion of traffic diversion setup
• Major structural work for flyover and underpass
• Final road surfacing and safety inspections
• Official opening for public use

Traffic Impact & Public Concerns

While the Islamabad T-Chowk Flyover & Shaheen Chowk Underpass promise long-term benefits, commuters and residents will face temporary challenges during construction.

• Expected Detours: Traffic will be diverted to alternate routes, particularly affecting Islamabad Expressway, Ninth Avenue, and adjacent service roads. Signage and temporary traffic management plans will be in place to guide drivers.
• Daily Commuter Impact: Peak-hour congestion is expected for students, office-goers, and local travelers, requiring additional travel time and patience during construction phases.
• Environmental & Urban Planning Concerns: Some residents have raised issues about tree cutting and the perception of increasing “concrete jungle” areas, emphasizing the need for green planning and mitigation measures.
• Public Feedback: Social media and local community forums reflect a mix of anticipation and concern, with residents welcoming long-term traffic relief but requesting careful handling of environmental and safety aspects.

Benefits for Islamabad

Islamabad T-Chowk Flyover and Shaheen Chowk Underpass are expected to bring significant improvements to the capital’s transport network:

• Reduced Congestion: Major traffic choke points, particularly at T-Chowk and Shaheen Chowk, will experience smoother flow, easing daily commutes.
• Improved Connectivity: Faster access to universities, government offices, and inner-city routes will benefit students, employees, and local travelers alike.
• Economic & Environmental Impact: By minimizing idle time in traffic, commuters will save on fuel costs, reduce vehicle emissions, and enjoy a more efficient, environmentally friendly commute.

Conclusion

Islamabad T-Chowk Flyover and Shaheen Chowk Underpass , set for groundbreaking in early September 2025, will ease congestion, improve connectivity, and benefit daily commuters. While temporary disruptions are expected, the long-term advantages for Islamabad’s transport network are significant. Stay updated with our detailed coverage on CDA projects in the capital.
