Outer Ring Road for Thiruvananthapuram Alignment of Outer Ring Road: Navaikulam to Vizhinjam with link to Mangalapuram Typical Cross section for Outer Ring Road: Outer Ring Road for Capital City of Thiruvananthapuram Revised Initial Screening Report Synopsis of Revised Initial Screening Report PS-1 General Government of Kerala in 2002-03 approved a set of projects under Capital Region Development Project (CRDP) for the planned development of the Capital City. These projects are under various stages of implementation such as “Trivandrum City Road Improvement Project” comprising development, operation and maintenance of approx. 42 kms of important city roads. The Government has now decided to take up additional projects as Phase-II to supplement the above with the objective of sustainable improvement of urban environment of the Capital Region and to take care of the future development of the Capital City. Government of Kerala (GoK) through the Phase-II of Capital Region Development Project (CRDP) has taken up city-region infrastructure projects such as: Improvement of existing roads, Construction of ring roads and link roads; Preparation of parking policy and building parking places; Cleaning of waterways and water bodies; Environmental improvement of Markets, Shopping Streets and Parks; Greening the city by planting 1 lakh trees in 5 years; Improvement of connectivity (Broadband, Wi-Fi, etc.); Revitalization of Heritage commission, highlighting of Landmarks and distribution of Music and Art Circuit; Development of alternate source of energy, provide UG cabling and ring main, etc. Providing drinking water facility (100%) for all 100% coverage of sewerage system The High Power Committee under the Chairmanship of Hon’ble Chief Minister has decided to take up four priority projects, these are: Improvement of existing roads, construction of ring roads and link roads Preparation of parking policy and building parking places Environmental improvement of markets, shopping streets and parks Greening the city by planting 1 lakh trees in 5 years M/s. IL&FS Township & Urban Assets Limited., have been retained by CRDP-II as Transaction Advisors for the establishment of the technical, economical, and financial viability of the Outer Ring Road (ORR) Project of Thiruvananthapuram City and develop the periphery into a Outer Area Growth Corridor (OAGC). PS-2 Objective of the Study The main objective of the Study is to establish the technical, economical, and financial viability of the project and prepare detailed feasibility project reports for the Outer Ring Road (ORR) Project of Thiruvananthapuram City and develop the periphery into an Outer Area Growth Corridor (OAGC). Page 1 of 35 Outer Ring Road for Capital City of Thiruvananthapuram Revised Initial Screening Report At this Stage, the initial screening report for the entire stretch from Paripally (near Navaikulam) to Vizhinjam along with a spur/link to Mangalapuram has been prepared. The limitation of the initial screening report are as follows: 1. Horizontal alignment is fixed based on the Digital Elevation Model and Contour Map (1 meter level interval) as generated from processed aerial LiDAR data acquired through primary survey. 2. Traffic data is from secondary sources. Primary Traffic Survey will be carried out in the next few weeks and results of the same shall be reported in the draft Detailed Project Feasibility Report. Detailed Feasibility Project Report (DFPR) Study for Outer Ring Road (Navaikulam to Vizhinjam along with a spur/link to Mangalapuram) shall be completed based on the comments on this report from various departments. PS-3 Outer Area Growth Corridor Appreciation Outer Area Growth Corridor project is perceived as “A new township built alongside Outer Ring Road (ORR) similar to Special Economic Zone with proper Master Development Plan & special Development Regulations to attract Investments and Talents, has been taken up to achieve the following objectives: a) Accelerated, systematic and environmentally responsible development of peripheral areas to improve the quality of life of residents in the outer areas of capital region b) Offer direct connectivity and shorter commuting time from outer area and adjoining districts to the major economic hub of capital region-Vizhinjam Port and thus help decongest the core city area by reducing transit traffic. c) Provide adequate support infrastructure to spur ancillary economic activities to the major economic hubs at Vizhinjam (southern side of city) and Technopark-Technocity complex (northern side of city). PS-4 Project Location The ORR project is green-field project on the Outer Area of Thiruvananthapuram City on the eastern side for a length of about 78.880 Kms. The location plan of the project road section is given in Plate PS.1.

(ii) The ORR starts from National Highway no. NH66 (old NH 47) near Paripally (from Navaikulam) and end point is Vizhinjam Bypass/NH66 (direct connectivity to Vizhinjam Port) with a link between Thekadda to Mangalapuram. (iii) The length of the ORR is about 78.880 Kilometers, i.e Trunk alignment from Navaikulam to Vizhinjam: 65.630 Kilometers and Link alignment from Thekadda to Mangalapuram is 13.250 Kilometers. (iv) The right of way (RoW) for the ORR is 70 meters. RoW area of about 600 hectares shall be acquired for the ORR. (v) The land use along the stretch is of mixed in nature with agricultural, residential, cultural and commercial. (vi) Major built ups along the project road is limited to locations where proposed highway crosses the existing roads. 14 nos. of PUPs, 36 nos. of LVUs, 21 nos. of VUPs, 7 nos. of Flyovers are proposed for the main trunk of ORR. Similarly, 2 nos. of PUPs, 10 nos. of LVUs, 4 nos. of VUPs, 2 nos. of Flyovers are proposed for the Mangalapuram link. (vii) The proposed ORR alignment crosses an existing railway line near Balaramapuram. (viii) The details of the rivers/streams and ponds are presented in Table PS-1.
