Namakkal Bypass Road is an important highway corridor around Namakkal city. The existing bypass forms part of NH-44, formerly NH-7, and carries Salem-Karur through traffic around the busiest central streets. NHAI records identify it as an 8.4 km four-lane project.
Tamil Nadu Highways is also developing a separate 22.387 km bypass from Mudhalaipatti Pudur to Vallipuram. It is being implemented in phases and should not be confused with the operational NH-44 bypass.

Where Is Namakkal Bypass Road Located?
The existing NH-44 bypass lies around outer Namakkal on the Salem-Karur corridor, taking off near km 248+900 and ending around km 259+600 in older NHAI project documents.
It passes through or near Vallipuram, Mudalaipatti, Thummankurichi, Ayyampalayam Agraharam and Nallipalayam, keeping through traffic away from central Namakkal.
Connectivity of Namakkal Bypass Road
NH-44 gives Namakkal direct north-south connectivity towards Salem and Bengaluru, and towards Karur, Dindigul and Madurai.
Other radial roads connect Tiruchengode, Rasipuram, Mohanur, Trichy and Thuraiyur.
Salem and Bengaluru Connectivity
Northbound NH-44 connects Namakkal with Rasipuram-side approaches, Salem and onward Bengaluru. Namakkal district administration places Salem about 50 km from the city.
NHAI continues safety, service-road and black-spot improvement works on the Salem-Namakkal corridor.
Karur, Dindigul and Madurai Connectivity
Southbound NH-44 continues from Namakkal towards Paramathi, Karur, Dindigul and Madurai. Karur is about 45 km from Namakkal according to the district administration.
The Namakkal-Karur section is a four-lane tolled highway heavily used by buses, trucks and industrial traffic.
Tiruchengode and Erode Side Connectivity
Western roads provide access towards Tiruchengode and onward Erode-side destinations.
Travellers should leave NH-44 at the correct city or bypass junction rather than remain on the Salem-Karur carriageway if their destination is Tiruchengode.
Mohanur and Trichy Connectivity
Namakkal has direct road links towards Mohanur and onward routes towards Trichy.
For Trichy, the most practical route can depend on the exact starting point in Namakkal and current road conditions, so live navigation is useful.
Rasipuram and Sendamangalam Connectivity
Rasipuram lies north-east of Namakkal, while Sendamangalam provides access towards the Kolli Hills side.
These destinations are not reached simply by staying on the NH-44 bypass, so drivers should use the appropriate local junction and signed state-highway routes.
Railway Connectivity
Namakkal Railway Station serves the city on the Salem-Karur line.
The station is inside the urban area rather than directly on the outer highway bypass. Autos and cabs are the practical transfer options between the station and NH-44-side bus or highway pickup points.
Airport Connectivity
The district currently lists Salem Airport at about 72 km, Trichy International Airport at about 93 km and Coimbatore International Airport at around 150 km.
The best airport choice depends on flight availability and destination. For a fixed flight, travellers should allow extra time for highway traffic and city approaches.
Bus and Local Transport
Government and private buses connect Namakkal with Salem, Karur, Erode, Trichy, Madurai and Coimbatore. Autos and cabs connect the bypass with the bus stand and railway station.
Private-bus boarding references can vary between Namakkal town, highway junctions and bypass-side points. Passengers should follow the exact landmark on the current ticket rather than relying only on the words ‘Namakkal Bypass’.
Nearby Areas Around Namakkal Bypass
Mudalaipatti, Nallipalayam, Vallipuram and Rasampalayam are important bypass/highway references.
Central Namakkal, the Anjaneyar Temple, Namakkal Fort, markets and railway station are reached by leaving the bypass through city-entry roads.
Shops and Daily Facilities
NH-44 approaches have fuel stations, restaurants, tyre shops, workshops and transport-related businesses.
For hospitals, banks, large markets and a wider choice of hotels, central Namakkal remains the main service area.
Traffic Conditions on Namakkal Bypass
The existing NH-44 bypass carries heavy truck, bus, car and local traffic, with slowdowns possible near major junctions.
NHAI continues black-spot, underpass and service-road work on the Salem-Namakkal-Karur corridor, so current lane signs should be followed.
New 22.387 km Namakkal Bypass Project
Tamil Nadu Highways is separately developing a 22.387 km town bypass from Mudhalaipatti Pudur near km 248/0 of old NH-7 to Vallipuram near km 259/820.
The project is phased. Government communications listed Phase II and III among ongoing works, while Phase IV covers km 12/0-16/0 and Phase V km 16/0-22/387.
Phase IV and Phase V: Current Position
Phase IV, km 12/0-16/0, was tendered in August 2025 at about Rs 37.95 crore.
Phase V, km 16/0-22/387, was tendered at about Rs 53.07 crore. The outer bypass should therefore still be treated as a phased project, not a fully completed 22.387 km road.
Until the Highways Department announces full commissioning, travellers should continue to rely on the existing operational NH-44 bypass and currently open local roads.
Toll Information
Rasampalayam Toll Plaza lies around km 259+500 on the NH-44 Namakkal-Karur section.
A fresh fee notification was issued on August 28, 2026 for the Namakkal-Karur section, so current FASTag/NHAI rates should be checked.
The new 22.387 km state bypass is not a separately operational tolled road at present, so no final standalone toll should be assumed for it.
Conclusion
Namakkal Bypass Road is best understood as two different projects. The existing 8.4 km NHAI bypass on NH-44 is operational and carries Salem-Karur through traffic around the city. Separately, Tamil Nadu Highways is developing a 22.387 km outer bypass from Mudhalaipatti Pudur to Vallipuram in phases. Namakkal Railway Station provides local rail access, Salem Airport is the nearest airport listed by the district, and Rasampalayam Toll Plaza serves the NH-44 Namakkal-Karur corridor. Until the larger state bypass is fully commissioned, motorists should continue to use the existing NH-44 bypass for through travel.
FAQs About Namakkal Bypass Road
Q1. Is Namakkal Bypass already open for traffic?
The existing 8.4 km NH-44 Namakkal Bypass is operational. The separate 22.387 km Tamil Nadu Highways bypass is still being developed in phases and should not be treated as fully open.
Q2. Are the 8.4 km bypass and 22.387 km bypass the same road?
No. The 8.4 km route is the older NHAI NH-44 bypass. The 22.387 km route is a separate state-highways project from Mudhalaipatti Pudur to Vallipuram.
Q3. Which bypass should I use for a Salem-to-Karur through journey?
Use the currently operational NH-44 route around Namakkal. Do not depend on the incomplete 22.387 km state bypass for through navigation.
Q4. Is there a toll near Namakkal Bypass?
Yes. Rasampalayam Toll Plaza serves the Namakkal-Karur NH-44 section. Keep FASTag active and check the latest applicable rate before travel.
Q5. Which airport is nearest to Namakkal?
Namakkal district currently lists Salem Airport as the nearest at about 72 km. Trichy International Airport, about 93 km away, may offer a wider choice of flights depending on the date.
Q6. Which railway station should I use from the bypass?
Namakkal Railway Station is the local station on the Salem-Karur line. Use an auto or cab from the bypass because the station is not directly beside the NH-44 carriageway.
Q7. Is Phase V of the new bypass complete?
Phase V was tendered for the km 16/0-22/387 section. The available official tender information supports treating it as part of the phased project, not as a fully commissioned open road.
Q8. Why is Namakkal getting another bypass when NH-44 already bypasses the city?
The newer 22.387 km state project is designed to create a broader outer connection between major radial roads and reduce local and heavy-vehicle pressure on the urban network. It is a separate project from the older NH-44 bypass.
