Solo–Kertosono Toll Road (Soker Toll Road) is part of Trans-Java toll road, where in the west it connects to Semarang-Solo Toll Road, and in the east it connects to Kertosono-Mojokerto Toll Road.

Route

Administratively, Soker Toll Road with a total length of 177.12 km comprise two segments, segment Solo-Mantingan-Ngawi and segment Ngawi-Kertosono. The length of Solo-Mantingan-Ngawi toll road is 90.1 kilometer, while the length of Ngawi-Kertosono is 87.02 kilometer. Hence, in the beginning, Soker Toll Road was designed as two separate toll roads. However, during its tender process, no investors showed interest in bidding these two toll roads except one bidder, which is PT Thiess Contractors Indonesia. In June 28, 2011, Toll Road Concession Agreement (PPJT) amendment has been signed in Jakarta.[1] With this concession agreement, segment Solo-Mantingan-Ngawi will be under PT Solo-Ngawi Jaya, while segment Ngawi-Kertosono will be under PT Ngawi-Kertosono Jaya. Both of this companies are subsidiaries of PT Thiess Contractors Indonesia. Since both of toll road concessions have been awarded to the same company, these two toll roads usually are referred as Solo–Kertosono Toll Road, or Soker Toll Road.

When commencing operation, Solo - Kertosono Toll Road, known as Soker Toll Road, will be the longest toll road in Indonesia. Solo–Kertosono Toll Road is the first Public-Private Partnership project in Indonesia's infrastructure. The PPP scheme has been used because, for the investor to fully finance the project, its financial internal rate of return on capital is low, at only 12 per cent, and the capital payback period, seen from the perspective of toll road business, will be very long because it is hampered by the people’s ability to pay the toll fees. In terms of financing, the completion of Soker Toll Road requires project costs to the tune of almost Rp 11 trillion, or more precisely Rp 10.98 trillion. These costs cover the cost of land acquisition amounting to Rp 1.85 trillion, the cost of construction undertaken by the government amounting to Rp 3.55 trillion, and the cost of construction by the investors amounting to Rp 5.57 trillion.[2]

Soker Toll Road itself will pass through eight regions, namely Boyolali Regency, Karanganyar Regency, Solo City, Sragen Regency in Central Java Province, and Ngawi, Madiun, Nganjuk and Jombang Regency in East Java Province.[3]

Construction

As part of public-private partnership deal, the government has to build one-third of the length of Soker toll road plus the whole length of land acquisition cost. This one-third length portion is split into two parts: The west end part with total length 20,9 km is located in greater Solo area, and the east-end part with total length of 40,1 km is in Kertosono, East Java Province.

For the land acquisition administrative purpose, Soker Toll Road is divided into 4 sections, namely Solman I and Solman II in Central Java Province, and Manker I and Manker II in East Java Province. In July 2012, the land acquisition of the each section is about 65 percent. Although all of land acquisitions are not yet finished, the road construction for section-1 has been commenced.[4]

The construction in the government-support portion has been started in 2009 in Solo area using national budget (APBN) by The Government. By the end of year 2011, Bengawan Solo Bridge as one of major bridges in Soker Toll Road (300 meter length) has been completed. Overpass Karangturi has been completed, together with the completion of 2,6 km toll road. The year-by-year activity is as follows:

In year 2012, a total of Rp 610 billion has been allocated by The Government to build almost all of structures in the west-end, and a portion of roads with total of length 7 km. In addition, one project is set in Kertosono-end, in the form of Brantas Bridge (250 meter) plus 1.5 km toll road. This package marks the beginning of East Java portion of Soker Toll Road construction. PT Thiess Contractors Indonesia has set a plan to start construction work in her investor portion by the end of 2012.,[5] however, it is unlikely that the plan can be implemented due to land acquisition problem.

There are many different versions of data about Soker Toll Road. However, according to Brawijaya, Ph.D, the project manager for its construction and also the former project officer of Soker Toll Road during design stage, the actual length of Soker Toll Road is longer than the information provided by many.[6]

Soker Toll Road has a total length of 183,3 km, including its access roads and addition length of 1.7 km in the east-end.

  1. Colomadu-Karanganyar Section: 1.7 km access road in Ngasem, Colomadu plus 20.9 km tol road with total cost Rp 1.8 trillion (government-support portion)
  2. Karanganyar - Saradan Section: 120 km with total cost Rp 5.57 trillion (investor portion)
  3. Saradan - Kertosono Section: 40.1 km with total cost Rp 1.7 trillion (government-support portion)

Thus, the total construction cost should be tuned by the government is Rp 3.55 trillion, and the total cost should be provided by the investor is Rp 5.57 trillion. The cost of land acquisition has increased from Rp 1.85 trillion to Rp 2.2 trillion. In terms of its feasibility, Soker Toll Road has Financial IRR 17,5% (with the government support), and Economic IRR 22%.

Junctions

By design, there are four interchanges in Central Java Province, and another four interchanges in East Java Province. These interchanges are:
