The latest published update, in July 2026, reported that girder installation for the first level had begun along the Cooum.

Question 2

What is the route of the Chennai Port Maduravoyal Expressway?

Accepted Answer

It begins at Chennai Port Gate 10 near Victory War Memorial, runs along the Cooum River to Koyambedu, then follows the NH-48 median along Poonamallee High Road to the Maduravoyal junction. Entry ramps are at Sivananda Salai and College Road; exit ramps at Kamarajar Salai and Spur Tank Road.

Question 3

How long is the Chennai Port Maduravoyal Expressway and what does it cost?

Accepted Answer

The expressway is 20.6 km long. All four construction packages are awarded to J Kumar Infrastructure at a total contract value of Rs 5,510 crore. NHAI's official estimate for the project is Rs 5,855 crore including all components.

Question 4

Why is the Chennai Port Maduravoyal Expressway delayed?

Accepted Answer

Three factors: the Water Resources Department's slow handover of Cooum river boundary land to NHAI, National Green Tribunal seasonal restrictions on work between October and December during monsoon periods, and traffic police curbs on daytime construction vehicle movement in Chennai.

Question 5

Which areas benefit most from the Chennai Port Maduravoyal Expressway?

Accepted Answer

Maduravoyal gains the most directly through its junction with the Bangalore-Chennai Expressway (NE-7), creating a port-to-highway logistics chain. Koyambedu benefits from the mid-corridor interchange. Egmore and Nungambakkam gain indirectly through relief from heavy vehicle traffic once the expressway is operational.

Question 6

How will the Chennai Port Maduravoyal Expressway affect real estate near Koyambedu?

Accepted Answer

Properties near Koyambedu saw approximately 9% appreciation in the year following the project's 2022 revival. However, construction disruption in the Koyambedu parclo interchange area continues through 2027; factor that into any near-term purchase decision near this junction.

Where does the expressway connect to the Maduravoyal bypass?

Accepted Answer

At the Maduravoyal junction, where NH-48 (Poonamallee High Road) meets the Chennai Bypass.
