Margalla Avenue Islamabad: Route, Extension Status & the Name Trap

Margalla Avenue is a road, not a housing scheme — and that sentence alone settles half the searches that land here. It is the ~33-km highway CDA runs along the foot of the Margalla Hills on Islamabad’s northern edge, designed to link Sangjani on GT Road (N-5) in the west with Bhara Kahu / the Murree Expressway (E-75) in the east. If you were looking for the DHA scheme, that is Margalla Enclave — a different thing, on the opposite side of the city. The full name-trap is untangled at the bottom.

What is actually open (dated)

• Main avenue: inaugurated 20 June 2023. The corridor runs behind the D and E sector belt — it is the reason D-12 and E-11’s access story changed.
• Iran Avenue section: the 5.5-km stretch from D-12 to E-11, opened 22 April 2024 (jointly inaugurated by the Iranian president and the PM — hence the name). This is the piece our D-12 guide and E-11 guide price against, and the frontage of D-12’s approved cricket-stadium site.
• History for perspective: planned in 2006, first works in 2012 with a June-2013 “deadline” — the corridor took over a decade longer than promised. Worth remembering whenever a completion date below is quoted as certain.

The 2026 story: the extension to the M-1 motorway

• What is being built: the missing western link so northern Islamabad reaches the M-1 without detouring onto Srinagar Highway or IJP Road. Per CDA and Dawn (6 May 2026): a three-lane carriageway each way, two-lane service roads, two underpasses, a bridge, and an interchange at Sangjani on GT Road.
• Who builds what: CDA executes the ~2.7-km section from GT Road to the Sangjani grid station; the Punjab government executes the ~2.5-km second phase from the interchange to the M-1 itself. Estimated cost was Rs 3.58 billion, with the lowest bid reported about a tenth below it.
• The dates, honestly: the Sangjani interchange was fast-tracked for 31 July 2026; the full CDA section carries a December 2026 target. As of late August 2026 we have not found an official ribbon-cutting announcement for the interchange — treat “open” claims as unverified until CDA says so. We update this line when it changes.
• Who gains: Dawn names D-12, E-11 and the F/G/H sectors as the direct beneficiaries — a straight run to the motorway instead of the Srinagar Highway crawl. In plot terms, it is one more dated entry on the access ledger of D-12 and E-11.

Margalla Avenue vs Margalla Road — same thing?

Yes. Official documents and news reports use both names for the same corridor (Dawn’s 2026 coverage says “Margalla Road extension”; CDA material and Wikipedia say “Margalla Avenue”). The D-12–E-11 stretch additionally carries the name Iran Avenue. Three names, one road — do not let a dealer present them as separate projects.

The “Margalla” name trap — four different things

• Margalla Avenue / Margalla Road — this page. A highway on the city’s northern edge, at the foot of the hills.
• DHA Margalla Enclave — a DHA plot scheme in CDA Zone IV on the south-east side (Jinnah Avenue corridor). Not at the hills; the name is branding. Its 3rd ballot closes 4 September 2026.
• Margalla Orchard — a separate FGEHA-SCBA scheme on Main Park Road (DHA joined September 2025). Also south-east, also not at the hills.
• Margalla Hills — the national park itself. Nothing inside it is legally for sale; anyone selling “Margalla Hills plots” is selling a story.
