Modern Bridge
The bridge's total length with approach ramps is 668 metres (bridge itself 262.5 metres, spans 47.25 + 168.0 + 47.25 metres). Its full width 38.4 metres, including a 24 metre road (6 lanes) and two 5-metre pedestrian lanes.
The eyebar chains are made of ODS steel (ОДС, Palace of Soviets Ordinary) rolled by NKMZ works, each link consisting of 4 centimetre thick, 93 centimetre wide strips. Chains are carrying two girders (each over 300 metres long), their ends anchored to massive concrete counterweights. Girders are crossed with 50-centimetre I-beams, spaced by 1.6 metres; these beams are covered with a concrete deck.
The bridge was represented on Soviet postage stamps twice – in March, 1939 and December, 1948. Visually unique (at least, in Moscow), Krymsky Bridge is one of the least effective in terms of material costs. It consumed nearly 10,000 tons of steel, or 1 metric ton per square metre of deck (itself having a very low ratio of area usage, 24 to 38.4).
The bridge deck was replaced in 2001. During repairs, traffic was restricted, but never closed completely.

Famous quotes containing the words modern and/or bridge:
“As they get more nuclear
And more bigoted in reliance
On the gospel of modern science ...”
—Robert Frost (1874–1963)
“Oh, who will now be able to relate how Pantagruel behaved in face of these three hundred giants! Oh my muse, my Calliope, my Thalie, inspire me now, restore my spirits, because here is the ass’s bridge of logic, here is the pitfall, here is the difficulty of being able to describe the horrible battle undertaken.”
—François Rabelais (1494–1553)
