BRIEF DESCRIPTION ON CHENNAI PERIPHERAL ROAD 1 Scheme and Authority Chennai is the Capital of Tamil Nadu, has grown as a perfect base in respect of institutions, information technology, automobile and hardware manufacturing. Due to growing volume of traffic in and around the City, there is an immediate need for improvement of infrastructure facilities. Government of Tamil Nadu is in the process of identifying and implementing projects to bridge the huge gap in the demand and supply of infrastructure projects. One of the major projects included in VISION 2023 is Chennai Peripheral Road. Chennai Peripheral Road is conceptualized to provide better connectivity around the city catering future traffic requirements and provide efficient commercial transportation by enhancing port connectivity. This road will facilitate container movement from southern districts to Ennore Port. The Government of Tamil Nadu have accorded administrative sanction for the work of preparation of DPR for forming Peripheral Road connecting Mahabalipuram to Ennore Port. Name of Work: Peripheral Road connecting Mahabalipuram to Ennore Port (via) Singaperumalkoil, Sriperumbudur, Thiruvallur, Thamaraipakkam, Periyapalayam, Puduvoyal and Kattupalli. 2 Necessity for forming Peripheral Road Chennai city is located on the coast of Bay of Bengal which makes the road layout in the metropolitan area is of radial pattern. There are 4 principal radial arterials, viz. NH-5, NH-205, NH-4, NH-45, to the north, north-west, west and south respectively. In addition, there are three more radial arterials,(i) along the coast on the northern side (Thiruvotriyur High Road), (ii) between NH-4 and NH-45 (Arcot Road) and (iii) along the south coast (ECR & OMR). The radial roads are congested and inadequate to handle the growing traffic need. The connecting road system, with lot of missing links, has put tremendous strain on the radial network. City has got three circumferential roads viz., Inner Ring Road, Chennai Bypass and Outer Ring Road which connects the radial roads. As the city is developing beyond the limits of these circumferential roads, a new circumferential road is required. Chennai Airport is the third busiest airport in India. The city is served by two major ports. - Chennai port is the largest in Bay of Bengal and India's second busiest container hub, handling automobiles, motorcycles and general industrial cargo. - Ennore Port currently handles cargo such as coal, iron ore, other bulk and rock mineral products and future expansion plans are on the anvil. Chennai city has got one more private sea port at Kattupalli near the northern town of Ennore. Road connectivity to the Ennore and Kattupalli ports needs to be provided from the radial roads without congesting the city roads. Also the upcoming regional industries require capacity augmentation in terms of traffic infrastructure. 3 Project Road The State Government of Tamil Nadu has identified already a tentative alignment for the proposed peripheral road. This alignment was studied along with other alternate alignments on the basis of technical and financial viability. The proposed alignment options were evaluated by the Technical Sub-Committee, Technical Committee and Steering Committee based on technical and financial viability. The alignment for Chennai Peripheral Road was approved by the Steering Committee and finalized by the Principal Secretary, Highways and Minor Ports, Government of Tamil Nadu on 09.07.2014. The Peripheral road will starts at Ennore Port and ends at Poonjeri Junction (km 56/800 of ECR) in Mahabalipuram. The proposed road will connect four National Highways – NH-5, NH-205, NH-4 and NH-45, and eight State Highways – SH-51, SH-50A, SH-50, SH-48, SH-57, SH-49B, SH-49A (OMR) and SH 49 (ECR). Length of proposed peripheral road will be around 133.381 km which is split into 5 sections. Section 1: Northern Port Access Road - Ennore Port to Thatchur on NH-5 Section 2: Thatchur on NH-5 to Start of Thiruvallur Bypass Section 3: Start of Thiruvallur Bypass to Sriperumbudur on NH-4 Section 4: Sriperumbudur on NH-4 to Singaperumalkoil on NH-45 Section 5: Singaperumalkoil on NH-45 to Mahabalipuram Section - 1: Northern Port Access Road from Ennore Port to Thatchur on NH-5 Feasibility Study Report for forming North Port Access Road (NPAR) from Northern Gate of Ennore port to Thatchur on NH-5 (km 30/270 ) with a connecting road to Tiruvottiyur-Ponneri-Panchetty Road was prepared already by NHAI. As requested by the Government of Tamil Nadu, NHAI handed over the Feasibility Report to the State Government to take the Project forward. GoTN appointed TNRDC as Managing Associate for the project and modified the alignment with additional access provisions as per the requirements of major stakeholders. The length of NPAR will be 21.12 km and the TPP link Road is 4.35 km. The proposed NPAR will have 4-lane divided carriageway with 2-lane service roads on both sides and the proposed ROW is 100m. TNRDC prepared already the updated feasibility report with land plan schedule which are adequate to implement the project on DBFOT basis. In order to avoid built-up section, HT lines and to accommodate the interchange at NH-5, the end of project road is shifted southwards to km. 29/000 of NH-5. As the alignment of NPAR from Ch. 17+300 to NH-5 is modified, the length of NPAR will be 20.900 km against the original length of 21.120 km. The link road from NPAR to TPP road for a length of 4.21km is also included in the project. Total length of the section is 25.11 km and is totally new formation. Section - 2: NH-5 at Thatchur to Start of Thiruvallur Bypass The entire section will be new alignment from km 29/000 of NH-5 near Thatchur to km 50/500 of SH-57 near Othikkadu Village. The length of section is 26.40 km. The alignment will cross SH-51 at km 9/100 and SH-50A at km 18/400. As the SH-57 from km 50/500 to km 56/900 is passing through 6 villages, to avoid social impact new alignment is proposed parallel to SH-57, behind the settlements, from km 56/900 near Velliyur Village to end of project section (i.e. km 50/500 of SH-57). The project road will have 6-lane with paved shoulder carriageway with 2-lane service road on both sides and the proposed right of way is 60m. Section - 3: Start of Thiruvallur Bypass to Sriperumbudur This section starts at km 50/500 of SH-57 i.e. start of Thiruvallur bypass and ends at km 42/250 of NH-4 in Sriperumbudur. Total length of this section is 30.60 km in which 9.6 km is improvement of existing SH-57 and balance is new alignment. Bypasses are proposed for Thiruvallur and Sriperumbudur towns and a realignment is proposed for Thodukkadu village. Thiruvallur bypass starts at km 50/500 of SH-57, crosses NH-205 at km 51/650 and SH-50 at km 16/900 and ends at km 38/900 of SH-57. Length of this bypass will be around 15.7 km. In order to avoid the built-up area of Sriperumbudur town, a new alignment is proposed along the Sriperumbudur tank bund from km 26/600 of SH-57 to km 42/250 of NH-4, for a length of 1.6 km. The realignment of Thodukkadu village is from km 27/600 to km 30/300 of SH-57, for a length of 2.85 km The project road will have 6-lane with paved shoulder carriageway with 2-lane service road on both sides and the proposed right of way is 60m. Section - 4: Sriperumbudur to Singaperumalkoil This section is stretch of SH-57 from NH-4 in Sriperumbudur to NH-45 in Singaperumalkoil, for a length of 23.80 km. Tamil Nadu Road Infrastructure Development Company Ltd. (TNRIDC), is widening this stretch of SH-57 to 6-lanes with service roads and Projects wing of Highways Department, Government of Tamil Nadu is constructing a ROB (in lieu of LC 47) with interchange (elevated roundabout type) on NH-45 at start of SH-57. Hence new vehicular underpasses only proposed within the available land to improve the safety. Section - 5: Singaperumalkoil to Mahabalipuram This section starts at km 47/400 of NH-45 in Singaperumalkoil, where the Interchange-cum-ROB is under construction and ends at Poonjeri Junction in Mamallapuram. Total length of this stretch is 27.471 km in which 2.0 km is improvement of existing SH-49B from km 11/200 to km 13/200 and balance is new alignment. The project road will be 4-lane with paved shoulder carriageway with 2- lane service road on both sides and the proposed right of way is 60m.
