The following areas, which are located near or at a river are potential material sources. These have mainly river gravel with cobbles and varying fractions of sand and fine material. During the site visit in November 2005, these rivers exhibited low flow with much of the riverbed dry and exposed. According to a number of locals interviewed, flow considerably increases during summer as a result of snowmelts from the surrounding mountains.

Qozlucay, Cengi - The Qozlucay river deposits are located in Garajuzlu village about 24 km north of Cengi. The borrow area, which can be accessed over a gravel road at km 57.5 on the right of the project road was utilized from 2004 until early 2005. The riverbed is estimated to have an average width of 50 meters. Materials will be extracted from the riverbed. The natural material from this borrow area can be used for fill, capping layer and granular subbase after processing and crushed stone obtained from gravel are suitable for use in bituminous mixture. Prior to construction detailed testing of the material has to be done to verify compliance with the specifications.
There is an abandoned accommodation facility, which is in very good condition while at the left riverbank the remains of a crushing facility still exists. The proposed borrow area is located some 400 meters from the village households.
The village has 14 households (about 56 persons). Majority of the residents are pensioners. Drinking water is supplied through a pipe, which taps river water some 8 km from the village. Agricultural fields utilize an irrigation canal originating some 4 km away. Along the access road, several small settlements (i.e., less than 10 houses) are found at a distance of 3 to 4 km from each other.
Areas surrounding the river are characterized by treeless landscapes covered with various species of grass. Wildlife species noted are common birds such as Crested Lark, Common Buzzard, Calandra Lark, Meadow Pipit, Rock Dove, Rook, Hooded Crow, Starling and House Sparrow.

Qozlucay, Maraza - The Qozlucay river deposits are located 24 km north of Maraza at the village of Hilmilli. The borrow area can be accessed over a surfaced/gravel road at km 111 to the right of the project road. The riverbed has an estimated width of 100 meters and has abundant deposits of gravel. Materials will be extracted from the riverbed. Gravel, natural sand and manufactured sand from gravel-sand mixtures can be obtained from this borrow area. Material can be used for fill, capping layer and granular subbase after processing and crushed stones obtained from gravel are suitable for use in bituminous mixture. Prior to construction detailed testing of the material has to be done to verify compliance with the specifications.
The village has a population of over 1,700 distributed among 415 households. Main sources of income are farming and livestock raising. Drinking water is sourced from springs. The access road leading to the village is surrounded by agricultural fields. The proposed borrow area is located approximately 300 meters from the village households.
Various species of grass cover the surrounding areas of the river. Wildlife species observed are common birds such as Crested Lark, Calandra Lark, Meadow Pipit, Hooded Crow, Starling, and Magpie.

Pirsaat Chay- The project road crosses the Pirsaat Chay river at km 115. It is the biggest river in the study corridor and crosses the road about 4 km east of Shamakhi from where it flows to a south-eastern direction. An estimated 15% of the flow comes from snow surface runoff, 48% from rain surface runoff and 37% from groundwater surface run-off. The riverbed is approximately 200 meters wide and primarily consists of gravel-sand mixture. The natural material can be used for fill, capping layer and granular subbase after processing and crushed stones obtained from gravel are suitable for use in bituminous mixture. Prior to construction detailed testing of the material has to be done to verify compliance with the specifications.
The river is currently being utilized as borrow area. Extraction activities were noted some 200 meters of the bridge towards the direction of Muganli and some 500 meters from the other bridge going to Maraza. During the site visit, much of the riverbed is exposed due to low flow. There are no houses in the immediate vicinity of the proposed borrow area. An asphalt plant is located near the eastern embankment of the river.
Vegetation adjacent to the river is composed of various grass species. Wildlife species noted are common birds such as Magpie, Rook, Hooded Crow, Starling, and House Sparrow. During the field visit in November 2005, a large flock of Rock Doves (about 3000 individuals) was noted on the riverbank.
Results of interviews with some locals residing in the vicinity of the potential borrow areas in Cengi and Maraza show that the river is not being utilized for fishing purposes. However, in Pirsaat Chay, some residents are said to catch fish for sustenance during the months of April to July when water level is high. Common fish species that may occur in the area are Caucasian Chub (Leuciscus cephalus orientalis), Kura's Barbel (Barbus curi), Caucasian Bleak (Alburnus charusini), Bitterling (Rhodeus sricous), Sazan (Cyprinus carpa), Kura's Loach (Nemachilus brandti). No threatened fish species are found in the rivers and streams in the region.
The traffic study conducted for the 124 km section of the Baku-Shamakhi road show that the average annual daily traffic in 2005 is estimated at 6,378. From 2005 to 2009 (opening year), the average annual change is estimated at 12.8%. Between 2009 and 2014 the annual change is expected at around 7.7% and at 5.9% between 2014 and 2029 (design year).
3.5Proposed Schedule for Implementation
The Project is scheduled to commence in mid-2006 and is forecasted to take 3 years until its completion in mid-2009.
