13 bridges, totaling 8 km were constructed with 1,777 precast, prestressed, posttensioned and hybrid type of beams. 312 thousand m3 of concrete and 70 thousand meter of piles were placed during the construction of bridges. Due to challenging and mountainous terrain, a 5.75 km meter long Lepence Bridge was constructed along a deep narrow valley accommodating Lepence River and Souther Part of Route 10 Railway Track Line. Design and construction of the bridge including very detailed geotechnical investigation is completed in 18 months.

Due to the complex geology on the terrain and deeper soil investigation requirements, geotechnical investigations, including 16,000 meter of boreholes, were carried out with complete attention by a number of teams performing extensive investigations. 200 thousand meter of active and passive anchors with different thickness of shotcrete works have been performed in order to stabilize deep cut slopes along the alignment.

Climate conditions were of a big concern. During March 2016, despite the heavy rainfall, the project team proceeded with its construction works associated with utility relocation as well as earthworks, structures, drainage, surveying, finishing, and manufacture & operations departments.

Utilities along the project were also one of the challenges. The utility lines had been investigated and identified on site. There existed high voltage lines, power lines and various sewage, water supply and irrigation lines. The design and relocation of some utility crosses underneath the motorway had been completed while others had commenced. 350 utility lines have been relocated and handed over to local authorities and service providers on PROJECT DETAILS PROJECT DESCRIPTION behalf of the Employer.

ACCOMPLISHMENTS: • The largest public contract UNIQUE CHALLENGES ever signed in Albania • Reduces transportation time The most challenging part of the whole corridor was the segment between Rrëshen from 8 hours to 2 hours and Kalimash, which is around 61 km long. Before the motorway, transportation was provided by poor old mountain road and travel time was eight hours. The Rrëshen - Kalimash Motorway’s main purpose is to serve as a faster and safer route through the mountainous region. Difficult terrain conditions and harsh climate conditions were two big challenges. To cross this difficult terrain, bridges, viaducts and tunnels were designed and constructed. Due to the 800 m of overburden on top of the tunnel, it was not possible to reach anywhere across the tunnel alignment except the entrance and exit locations. In order to reach portals of the tunnel, 17 km of service road were constructed. The Commodity UoM Total Commodity UoM Total service road was closed for 3 months in the year due to the harsh weather conditions. The total service road constructed for this project is 92 km.
