1 SRI LANKA Road Network Assessment 20 February 2005 Page 1 of 10

2 By: Road Network Assessment East Coast South Coast North Coast Date Surveyed: Weather conditions during survey: Dry and sunny The survey covers the tsunami affected districts predominantly situated on the south and east coast of the island. These include: Galle District, Matara District, Hambantota District, Ampara District, Batticaloa District, Trincomalee District, Mullaitivu District, and Jaffna District. The road network including bridges along the tsunami affected coastline was assessed under a number of criteria. The network was examined from an operational perspective to establish repair priorities that would best benefit humanitarian operations. The assessment included identifying major obstacles and bottlenecks for road transportation. Cost estimates for road and bridge emergency rehabilitation have been provided but it must be stressed that these improvements will only provide short term benefits. Time pressures have not allowed any detailed strategic analysis of the network. Trincomalee/Batticoloa/Pottuvil East Coast According to the UNHCR and WFP Offices in Trincomalee the MSR (main supply route) from Trincomalee to Batticoloa is as follows: Trinco-Kantale-Somapura-Sunkankuli-Kathiravelli-Vakarai-Panichchankeni-Kakkaville- Vaiaichchenai-Chenkaladi-Batticoloa-Pottuvil The length of the road from the A6/A15/A4 Junction at Trincomalee to Pottuvil is approx. 200km. This was the route for freight and large vehicles prior to the tsunami on the 26 th Dec 04 because of the poor condition of the A15 between Trincomalee and Sunkankuli. The situation on the A15/A4 was exacerbated by the tsunami and has increased the importance of this MSR. The road from Trincomalee involved crossing the Pawara Ar river by ferry at Verugal which was also the situation prior to the tsunami. The A15 was not passable at Panichchankeni because of the damage to the bridge. In order to get to the southern side of the bridge we had to travel back to Kantale, Habarana, Polonnaruwa which involved a journey of approx 240km that took 5hrs. Relief agencies were loading goods on boats from trucks at Panichchankeni in an effort to get them to the other side. The erection of a temporary Bailey Bridge at Panichchankeni is the most important infrastructural item required at present along the A15/A4. Page 2 of 10

3 Panichchankeni Bridge The road from the southern side of Panichchankeni to Pottuvil was passable because of the erection of several temporary bridges and the repair of damaged causeways and roads. There are a number of weight restrictions on the bridges and the roadway is only wide enough for single vehicles in many areas. The repairs were ongoing at the time of the assessment. Page 3 of 10

4 South Coast Kalutara-Galle-Matara-Hambantota-Debarawewa-Kirinda-Palatupana The MSR(main supply route)a2 from Colombo to Palatupana is as follows: Colombo-Kalutara-Galle-Matara-Hambantota-Debarawewa-Kirinda-Palatupana. The length of the road from Kalutara to Palatupana is approx. 250km. This is a two lane carriageway (one lane in each direction) with a bitumen macadam surface. The road follows the coast to Tangalle, moves inland and then touches the coast at Hambantota before going inland again to Debarawewa and then follows the coast from Kirinda to Palatupana. The railway runs parallel to the A2 as far as Matara. The road from Colombo to Galle is in reasonably good condition with two temporary bridges. These Bailey bridges are capable of taking 30 ton and they are not restricting traffic in either direction. The road from Galle to Matara is in good condition. A temporary SS Bailey bridge was erected on the eastern direction of the carriageway as a result of the collapse of one section of a bridge. The temporary bridge is capable of carrying 30 ton but there are no signs in-situ. SS Bailey Bridge Ahangama The road from Matara to Hambantota had suffered some damage but there was evidence of repair work being undertaken. A contractor was laying 2km of wearing course east of Matara and three (3) no. crews of approx fifty (50) personnel were working on the drains and ditches at the side of the road. Pothole filling and surface dressing was also taking Page 4 of 10

5 place at regular intervals. All of the above work was being supervised and coordinated by the RDA. There was no evidence of any significant damage occurring to the bridges. The road from Hambantota to Kirinda was inland and was not affected by the tsunami. There were two locations were traffic was restricted. The first a culvert that was under repair although there was no activity on that day and the second a bridge that could only accommodate traffic in one direction at a time. Culvert at Welligatta A contract for 10km of new road between Wirawila and Debarawewa had recently been completed and the standard of construction was excellent. The road included hard shoulders, drains, road markings, road signs, etc. New Road Wirawila-Debarawewa The road from Kirinda to Palatupana follows the coast and is in poor condition. The carriageway width is less than 4.0m in many areas which does not permit vehicles to pass. Page 5 of 10

6 The road network from Colombo to Palatupana along the coast has largely been unaffected by the tsunami. However the road has limited potential for further development and is presently carrying more vehicles than the design capacity. Page 6 of 10

7 North Coast Trincomalee-Kumpurupiddi-Pulmoddai-Eramadu The road from Trincomalee to Eramadu is approximately 80km long and on the route there are three major bridges(>40m), two minor bridges, two causeways and two ferry crossings. The road follows the coast from Trincomalee to Mullaittivu but because of the security regime access north of Pulmoddai and south of Mullaittivu is restricted. As a result the assessment of the coast road terminated at Pulmoddai and continued inland to Eramadu. The assessment started at the A6/A15 Junction which was the same starting point for the Eastern road assessment completed on 29 th Jan 05. The road from A6/A15 Jn to Kumpurupiddi is in reasonably good condition with a bitumen macadam surface. The average road width is 4.0m. The road from Kumpurupiddi to Eramadu has no surface finish and consists only of a sub-grade. The average road width is 3.5m. The three major bridges and one minor bridge are capable of taking 20ton vehicles. However one of the minor bridges, the causeways and the ferry crossings are only capable of taking passenger vehicles Page 7 of 10

8 Mullaittivu-Puthukkudiyiruppu-Velikkandal-Paranthan A35 The road from Mullaittivu to Paranthan is approximately 54km long and on the route there are thirteen bridges and two causeways. Access south of Mullaittivu was not granted due to the security regime in place. The assessment started at the A35/A34 Junction. The Ministry of Relief, Rehabilitation and Reconstruction has a programme for bridge replacement in the North East. Five bridges along the Mullaittivu-Paranthan route are to be replaced, four of which are completed and the other one is well advanced. The remaining eight bridges are in good condition although they do not have the same load capacity as the new structures. One of the causeways has collapsed and while it is not a hindrance to traffic at the moment it will cause problems when the weather deteriorates. This causeway should be replaced with a similar bridge to the others. The road is in good condition with a bitumen macadam surface. The average width of the road is 6.0m. Page 8 of 10

9 North Coast:Jaffna-Kilinochchi A9 The road from Kilinochchi to Jaffna was not assessed in any detail apart from the bridges. The Ministry of Relief, Rehabilitation and Reconstruction has a programme for four bridges to be replaced along the route. Three bridges are completed and the groundworks are well advanced on the remaining one. The condition of the road is good with a finished surface of bitumen macadam. The A9 at Navatkuli is closed due to the bridge under construction on the route to Jaffna. As a result of the road closure a detour of approx 12km via Kopai into Jaffna will be in place for the next 16 weeks. The average road width of the A9 is approx 6.5m, but the average road width on the detour route is approx 5.0m. Page 9 of 10
