Hi guys, trying to finish the crossword rather late in the day. Have looked through all the posts so far I think but still hoping for answers to 8 Down Urban motorway (US) E_P_E_S_A_ ; 10 Down SIght around the autumn equinox (7,4) H_R_E_T/_O_N ; 23 Down With no understanding (8) _L_E_E_S
Help gratefully appreciated!
