 Summary:
 This work presents alternative solutions city road at the junction of the main road M4 and transversal T8 in Tuzla. Option 1, is defined by the planned reconstruction of the main road M4 at this stage, given that it is located in a horizontal curve. The reconstruction of the main road M4 predicted upgrade two traffic lanes and correction elements horizontal geometry and the vertical alignment over a length of 800 m. Transversal to T8 with bright height of 4.50 m passing beneath the reconstructed highway M4, respectively, the main road to crossing the overpass over the mentioned intersection. Connection leveled roads would be enabled by building two ramps one ascending-descending, and one upward. Option 2, is defined on the same concept as the variant 1, but without further intervention on the highway M4 except for corrections relating to the provision of the necessary clear height between grade separated junctions. Also, the connection T8 and M4 is achieved by building two ramps one downward and one upward and over the reconstructed two-way road on the north side. Option 3, is defined as a two-lane roundabout with a single-lane entryway /outputs width of 4.5 meters on the main road M4, and two-lane entryway /outputs width of 5.4 meters with the retention of the central islands of the transversal T8 because in this way does not compromise comfort cross section trasnferzale. The horizontal geometry is designed to meet the mobility of the relevant vehicle. Round about is down south along the direction transversal T8 to obtain adequate space, as well as to avoid problems with fitting in the current situation, ie. so as not to jeopardize the residential buildings on the north side. The paper presents elements of the plan and profile elements by variants as well as construction costs including the cost of expropriation.
