Puh Bridge over Drava in Ptuj (Extradosed bridge)
PUH BRIDGE OVER DRAVA IN PTUJ
Puh bridge is part of the southern bypass of Ptuj. It has two lanes and separate lanes for cyclists and pedestrians. The bridge is characterized by severe restrictions and environmental conditions, and preserves the old city views, dominated by the old castle above the city center.
These restrictions limited the height of the structure (pylons) to a maximum of 10 meters. The bridge was designed as a extra dosed bridge, which are similar in appearance to cable-stayed bridges, but have much lower columns. It stands on two buttresses and four intermediate pillars, three of which are in water and one on dry land. The construction is a continuous externally prestressed box construction, which allows lower pylons through which 4 harps are tensioned. The bridge is crossing the Drava River in a rather sharp curve.
The entire construction is a single brake unit with dilatations on both end struts, which lowers the cost of construction and reduces maintenance costs. A special feature of the bridge is its ambient lighting.

PUHOV MOST ČEZ DRAVO NA PTUJU
Puhov most je del južne obvoznice Ptuja. Most ima dva vozna pasova in od vozišča ločena pasova za kolesarje in pešce. Oblika mostu izhaja iz okoljskih pogojev in strogih omejitev glede umestitve ob staro mestno jedro Ptuja, nad katerim dominira grad.
Te omejitve so omejile višino konstrukcije (pilonov) na največ 10 metrov. Most spada med t.i. »extradosed« mostove, ki so na pogled podobni kabelskim mostovom, vendar imajo precej nižje stebre. Stoji na dveh opornikih in štirih vmesnih stebrih, od katerih so trije v vodi, eden pa na suhem. Konstrukcija je kontinuirna zunanje prednapeta škatlasta konstrukcija, kar omogoča nižje pilone, preko katerih so napete 4 harfe. Most preči reko Dravo v precej ostrem zavoju.
Celotna kostrukcija predstavlja eno samo zavorno enoto z dilitacijami na obeh krajnih opornikih, kar znižuje ceno gradnje in zmanjšuje stroške vzdrževanja. Posebnost mostu je tudi ambientalna osvetlitev.
