  Based on 85 pb$^{-1}$ data of \ppbar collisions at $\sqrt{s}=1.8$ \tev\
collected using the D{\O}detector at Fermilab during the 1994-1995 run of the
Tevatron, we present a direct measurement of the total decay width of the \wb\
boson, $\Gamma_W$. The width is determined from the transverse mass spectrum in
the $W \to e+\nu_e$ decay channel and found to be $\Gamma_W = 2.23^{+ 0.15}_{-
0.14}$(stat.)$\pm 0.10$(syst.)GeV, consistent with the expectation from the
standard model.
